Answer:
Option C
Explanation:
From Lentz's law, the direction of induced emf in a circuit is such that it opposes the magnetic flux that produces it.
So, if the magnetic flux linked with closed-circuit increases the induced current flows in a direction so as to develop a magnetic flux in the opposite direction of the original flux.
If the magnetic flux linked with a closed circuit decreases then the induced current flows in the same direction of the original flux. So, the induced emf has not the direction of its own
