Assertion: Super conductors can be easily levitated in strong magnetic field.
Reason: Magnetic susceptibility of super conductor is extremely positive.

View answer and explanation

Correct option: C

If Assertion is True but the Reason is False

Option C (If Assertion is True but the Reason is False) is correct because superconductors can be levitated, but their magnetic susceptibility is extremely negative (not positive).
