loader
C
A = B = C
loader
D
A < B > C
loader

Solution

The correct option is A A > B > C

Stronger the magnet, greater will be the iron filings sticking on them. The magnetic strength of a bar magnet will be maximum at its ends. So from the figure, it is clear that  the strength of the bar magnets will be in the order A > B > C.
