Which of the following statements about a series LCR circuit connected to an ac source is correct?

These are the options for the question :Which of the following statements about a series LCR circuit connected to an ac source is correct?

(A) If the frequency of the source is increased, the impedance of the circuit first decreases and then increases.
(B) If the net reactance (X, – Xg) of circuits becomes equal to its resistance, then the current leads the voltage by 45°.
(C) At resonance, the voltage drop across the inductor is more than that across the capacitor.
(D) At resonance, the voltage drop across the capacitor is more than that across the inductor.

The correct answer is -(B) If the net reactance (X, – Xg) of circuits becomes equal to its resistance, then the current leads the voltage by 45°.
