Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
$I_{d c} = \frac{V_{d c}}{r}$ ( $r =$ internal resistance of inductor)
$I_{a c} = \frac{V_{a c}}{Z} = \frac{V_{a c}}{\sqrt{r^{2} + X_{L}^{2}}}$
If $V_{d c} = V_{a c}$ , then, $I_{d c} > I_{a c}$
