Solution

The correct option is A Energy
Lenz law is consistent with conservation of energy.
Lenz's Law states that an induced voltage will always act to appose the change that caused it.
Thus there is a work done is moving coils against the repulsive force. So we need to provide external energy to do this work. This energy is converted into electrical energy and then dissipated as heat in the loop by Joule heating produced by the induced current.
