Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The capacitive reactance of the capacitor is given by

$X_{C} = \frac{1}{ω C} = \frac{1}{2 π f C}$
So this is infinite for dc $(f = 0)$ and has a very small value for ac. Therefore a capacitor blocks dc.
