An ac source is connected to a capacitor C. Due to decrease in its operating frequency :
Answer: (C) displacement current decreases.
$X_C = \dfrac{1}{2\pi fC}$, so lowering the frequency increases the reactance.
The current in the circuit, $I = \dfrac{V}{X_C}$, therefore decreases. Between the plates, the displacement current equals the conduction current, so the displacement current also decreases.
