Answer
(a) Clockwise at 1, zero at 2, Counterclockwise at 3 (b) Choice I.
Work Step by Step
Since the magnetic flux is increasing at instance 1, the current must go in a direction that opposes flux, which is counterclockwise. There is no change in flux at instance 2, so the current is zero. Since the magnetic flux is decreasing at instance 3, current must go in the direction caused by the magnetic field, which is counterclockwise.
