Resonance, Bandwidth & Q Factor

A series $L\text{-}C\text{-}R$ circuit is connected to a source of A.C. current. At resonance, the phase difference between the applied voltage and the current in the circuit, is

Show answer and solution

Answer: (b)

At resonance $X_L = X_C$ , so $\tan\phi = 0 \Rightarrow \phi = 0$ .
So the answer is (b) zero.
