Flux through the loop decreases as the magnet is withdrawn.
There fore to prevent this change(Lenze's Law), the induced current flows in such a direction that a north pole is induced at the left side of the coil, and it attracts the south pole of the retreating bar magnet.
Hence the current as seen from the retreating bar magnet side is counterclockwise.
Therefore this time, the induced current flows from right to left in the current meter.
The answer is A) to the left, and the primary flux through the coil is decreasing.
