Correct Option(a) electromagnetic induction in the aluminium plate giving rise to electromagnetic damping.
Explanation:
According to Lenz,s law, electromagnetic induction takes place in the aluminiumplate due to which eddy current is developed which oppose the motion or vibrations of the coil.
This causes loss in energy which results in damping of oscillatory motion of the coil.
