What is the resonance condition in a series RLC circuit when analyzed in the frequency domain?

Correct option is C

​$$\text{In a series RLC circuit, resonance occurs when the inductive reactance } X_L \text{ equals the capacitive reactance } X_C : \\[8pt]X_L = X_C \\[8pt]\text{That is:} \\[6pt]\omega L = \frac{1}{\omega C} \\[10pt]\text{At this frequency:} \\[6pt]\bullet \ \text{The reactive parts cancel each other} \\[4pt]\bullet \ \text{The circuit impedance becomes purely resistive } (Z = R) \\[4pt]\bullet \ \text{Current is maximum}$$​​
