The door holding apparatus of claim 1, wherein, the fixation unit further includes: a bonding unit configured to be selectively bonded to an upper portion of the body, to thereby couple the fixation unit to the body, anda fixation plate protruding from the bonding unit and from a front surface of the body, to provide the first fixation unit and the second fixation uniton the fixation plate to selectively hold the first holder coupled to the first door and the second holder coupled to the second door. 3. The door holding apparatus of claim 2, wherein, the first magnet is provided to be moved in upward and downward directions in the first holder, to allow the first fixation unit to selectively hold the first holder, andthe second magnet is provided to be moved in upward and downward directions in the second holder, to allow the second fixation unit selectively hold the second holder. 4. The door holding apparatus of claim 3, wherein, the first fixation unit is formed by a steel plate, and is placeable in a location corresponding to the first magnet, to thereby selectively hold the first holder with the moving first magnet. 5. The door holding apparatus of claim 4, wherein, when the first door is opened, and when the first holder is moved so that the first magnet is placed in a location corresponding to the first fixation unit, the first magnet is moved upward by magnetic force interacting with the first fixation unit so that the first fixation unit holds the first holder with the first magnet moved upward, thereby fixing the first door. 6. The door holding apparatus of claim 5, wherein, when the first magnet is away from the location corresponding to the first fixation unit, the first magnet is moved downward to allow the first door to be easily rotated. 7. The door holding apparatus of claim 6, wherein, when the second door is opened, the first fixation unit is placed in a location away from a moving path of the second magnet. 8. The door holding apparatus of claim 3, wherein, the second fixation unit is formed by a steel plate, and is placeable in a location corresponding to the second magnet, to thereby selectively hold the second holder with the moving second magnet. 9. The door holding apparatus of claim 8, wherein, when the second door is opened, and when the second holder is moved so that the second magnet is placed in a location corresponding to the second fixation unit, the second magnet is moved upward by magnetic force interacting with the second fixation unit so that the second fixation unit holds the second holder with the second magnet moved upward, thereby fixing the second door. 10. The door holding apparatus of claim 9, wherein, when the second magnet is away from the location corresponding to the second fixation unit, the second magnet is moved downward to allow the second door to be easily rotated. 11. The door holding apparatus of claim 10, wherein, when the first door is opened, the second fixation unit is placed in a location away from a moving path of the first magnet. 12. The door holding apparatus of claim 2, wherein, a stopper is provided in the fixation plate to limit a rotation angle of the second door so that the second door is prevented from being rotated open at more than a 90 degree angle. 13. A refrigerator comprising: a body;a first door provided to be rotatable around a point of rotation in a front of the body and provided with an opening;a second door provided to be rotatable in a front of the first door to open or close the opening;a first holder coupleable to and detachable from the first door;a second holder coupleable to and detachable from the second door; anda fixation unit coupleable to and detachable from the body, the fixation unit including: a first fixation unit placed at a first distance from the point of rotation, to selectively fix the first door rotated open at a first angle by selectively holding the first holder coupled to the first door while the fixation unit couples to the body and the first holder couples to the first door, anda second fixation unit placed at a second distance other than the first distance from the point of rotation, to selectively fix the second door rotated open at a second angle different from the first angle by selectively holding the second holder coupled to the second door while the fixation unit couples to the body, the first fixation unit is selectively fixing the first door open at the first angle and the second holder couples to the second door. 14. The refrigerator of claim 13, wherein, the fixation unit further includes: a bonding unit coupleable to and detachable from a portion of the body, to thereby couple the fixation unit to the body, anda fixation plate protruding from the bonding unit and from a front surface of the body, to provide the first fixation unit and the second fixation unit on the fixation plate to selectively hold the first holder coupled to the first door and the second holder coupled to the second door. 15. The refrigerator of claim 14, wherein, the first fixation unit and the second fixation unit are formed by a steel plate,a first magnet is provided to be moved in upward and downward directions in the first holder, to allow the first fixation unit to selectively hold the first holder, anda second magnet is provided to be moved in upward and downward directions in the second holder, to allow the second fixation unit to selectively hold the second holder. 16. The refrigerator of claim 15, wherein, when the first door is opened, and when the first holder is moved so that the first magnet is placed in a location corresponding to the first fixation unit, the first magnet is configured to be moved upward by magnetic force interacting with the first fixation unit so that the first fixation unit holds the first holder with the first magnet moved upward, thereby fixing the first door. 17.
