Solution

The correct option is D $0.15 A$
According to Maxwell's hypothesis, a displacement current will flow through a capacitor when the potential difference across its plates is varying. Thus a varying electric field will exist between the plates and this displacement current is same in magnitude to the current flowing in outer circuit.
Here, the current in the outer circuit is 0.15 A. Thus $0.15 A$ will be the displacement current.
