When magnetic field crosses a turns of wire(take it as solenoid) it produces electric field. Hence it shows (a) is correct

And whose charges are based on its way or rotation whether clock wise or anti- clock wise. Thus (b) is correct

And a single turn wire experiences charges. Hence, (c) is correct

And a line under magnetic field induces no current. so, it is neutral. Which implies all (a),(b),(c) and (d) are correct
