A copper rod is suspended in a non-homogeneous magnetic field region. The rod when in equilibrium, will then align itself A. in the region where the magnetic field is strongest B. in the direction in which it was originally suspended C. in the region where the magnetic field is weakest and parallel to the direction of the magnetic field there D. none of these

Diamagnetic materials are repelled by a magnetic field. Applied magnetic field creates an induced magnetic field in the material which is in the opposite direction. This causes a repulsive force between the two.
Copper being a diamagnetic, the rod in equilibrium will align so that above mentioned force of repulsion is minimum.
Hence option C
