Solution

The correct option is B $B_{s} = 0$
Given: Magnetic field intensity:=B, Magnetic field inside superconductor= $B_{s}$
Solution: Diamagnet has a tendency to repel the magnetic field lines passing through it .
So, the perfect diamagnet or superconductor has no magnetic field lines passing through it .
Hence, $B_{s}$ =0
Correct option is B
