The Correct Option is B

Solution and Explanation

At resonance in a series LCR circuit, the inductive reactance and capacitive reactance cancel each other out. As a result, the impedance is purely resistive, and the power factor, which is the cosine of the phase angle between current and voltage, becomes 1, or unity.
