For a series LCR circuit, I vs $\omega$ curve is shown:

(a) To the left of ${\omega }_r$, the circuit is mainly capacitive.

(b) To the left of ${\omega }_r$, the circuit is mainly inductive.

(c) At ${\omega }_r$, impedance of the circuit is equal to the resistance of the circuit.

(d) At ${\omega }_r$, impedance of the circuit is 0 .
