In LCR circuit at resonance current in the circuit is \( 10 \sqrt{2} \mathrm{~A} \). If now frequency of the source is changed such that now current lags by \( 45^{\circ} \) than applied voltage in the circuit. Which of the following is correct :
(A) Frequency must be increased and current after the change is \( 10 \mathrm{~A} \)
(B) Frequency must be decreased and current after the change is \( 10 \mathrm{~A} \)
(C) Frequency must be decreased and current is same as that of initial value
(D) The given information is insufficient to conclude anything
