Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Current continues to flow in a super conducting coil even after switch off because at critical temperature, its resistance is zero so there is no hindrance to current flow.
Meissner effect says that at critical temperature magnetic field inside the conductor is zero i.e., $B = 0$ but this does not explain assertion.
