Answer:
HII MATE
HERE'S THE ANSWER
Explanation:
In case of dc, the frequency is zero, so the capacitive reactance Xc = 1/2πfc is infinite, hence there will no flow of current in the circuit and the lamp will not glow. If the capacitance of the capacitor is reduced, there will be no change in the circuit which makes the lamp to remain in similar position.
