Solution

The correct option is D Zero
Magnetic field lines do not pass through the diamagnetic sphere, as shown


Therefore, there will be no magnetic field inside the cavity of the sphere. Hence, the paramagnetic substance kept inside the cavity will experience no force.

So, option (D) is correct.
