Answer:

A

Explanation:

According to Lenz's law, induced current flows in such a direction that it opposes the change that caused it. Eg. if the north pole of a magnet is pushed towards one end of a coil, current will flow in a direction so as to create a north pole at that end. Since like poles repel, there will be some opposition. The work done in overcoming this opposition is what is converted into emf in the coil. It's the same thing here: Current in the circle has to flow in a direction to create a north pole below it. To do this, current must flow in the anti-clockwise direction viewing from below. Viewing from above, this is translated to a clockwise direction
