A magnet is suspended in the magnetic meridian with an untwisted wire. The upper end of wire is rotated through 180o to deflect the magnet by 30o from magnetic meridian. When this magnet is replaced by another magnet, the upper end of wire is rotated through 270o to deflect the magnet 30o from magnetic meridian. The ratio of magnetic moments of magnets is

• A.            1 : 5                                          
• B.            1 : 8
• C.            5 : 8                                          
• D.            8 : 5
