Correct option is
a
Anticlockwise
When we bring a north pole near a metallic ring applying Lenz's law the ring will behave as north pole so that repulsion occurs. So direction ofcurrent induced in it will be anticlockwiseas depicted above.

Explanation:
When the north pole of a magnet is brought near a metallic ring, the magnetic field lines of the magnet cut through the ring. This induces an electric field in the ring, which in turn leads to the flow of current in the ring. The direction of the induced current in the ring can be determined by applying Lenz's law, which states that the direction of the induced current is such that it opposes the change in the magnetic flux that causes it.
In this case, the north pole of the magnet is brought near the metallic ring. The magnetic field lines of the magnet cut through the ring from top to bottom. According to Lenz's law, the induced current in the ring will be in such a direction as to produce a magnetic field that opposes the field of the magnet. This means that the induced current will create a magnetic field that is directed from bottom to top.
Since a magnetic field that is directed from bottom to top is produced by an anticlockwise current, the direction of the induced current in the ring will be anticlockwise. Therefore, option A is the correct answer.
