C
D and C Only
D
A & D Only
Correct Answer
A & D Only
Detailed Explanation
If the reactance of a circuit is zero, it means that the impedance of the circuit is purely resistive. The reactance in a circuit is associated with either inductors or capacitors. To have zero reactance, it is possible that the circuit contains both an inductor and a capacitor, and their reactances cancel each other out, leaving only the resistive part and it is also possible if there are no inductors and capacitors then also the net reactance will be of resistance only. Therefore, the correct answer is:4 A and D only.
