Solution

The correct option is C III
The magnetic field due to the induced current will be oriented in such a way that it resists the change in the magnetic field produced by a permanent magnet. Therefore, the end Y of the coil will behave as the south pole. And the current will flow from the left according to the right hand thumb rule.

Hence, option C is the correct answer.
