Two circular coils P & Q are coaxially & carry currents `I_1` and `I_2` respectively (all direction are w.r.t. the observer)

A

If `I ' = 0` and P moves towards Q , a current in the same direction as I is induced in Q

B

If `I = 0` and Q moves towards P , a current opposite in direction to that of `I'` is induced in P

C

When `I ne 0` and `I ' ne 0` are in the same direction, then two coil tend to move apart

D

None of these
