If wattless current flows in the AC circuit, then the circuit is:
Answer: (B) Purely inductive circuit
Average power $P = V_{\text{rms}}I_{\text{rms}}\cos\phi$ is zero when $\phi = 90^\circ$, which happens for a purely inductive (or purely capacitive) circuit. Of the options, this is the purely inductive circuit.
