Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
As R, L and C are connected in series, the current through each element remains the same. Therefore, the peak value of current through each element remains the same. The peak value is as given in the concept attached.
The average power delivered by the source is the average power dissipated in the the resistor. Real power is not consumed either in inductor or capacitor. Real Power = I2rmsR
the reason and the assertion are not related.
