Concept:At resonance in a series LCR circuit, the inductive and capacitive reactances cancel each other.Explanation:At resonance, $X_L = X_C$.So the net reactance becomes zero.The impedance is given by:$$Z = \sqrt{R^2 + (X_L - X_C)^2} = R$$Thus, the impedance is minimum and the current is maximum.Since only resistance remains, the circuit behaves as a purely resistive circuit.Therefore, the current and voltage are in phase with each other.Answer:Option D: The current and voltage are in phase.
