EMI - Current in solenoid due to magnet

[cupid.callin]

Homework Statement

The Attempt at a Solution

Suppose that N pole of magnet is facing the solenoid
considering view from magnet
when the magnet moves close ... current is anticlockwise and increase from 0 to max till magnet reach starting of solenoid
when it enters the solenoid . some part will give opposite current and thus net current starts decreasing till 0 when magnet is in middle. now when magnet moves away ... the field due to south pole increase
so again current is anticlockwise

but answer is (c)

please someone explain me this
