Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Both assertion and reason are correct and the reason is the correct explanation for an assertion.
Example: Reactance of a capacitor is $x_{C} = \frac{1}{w C}$ is inversely proportional to w i.e frequency of source and direct current has $w = 0$
So reactance i.e resistance is $\infty$ infinite, thus blocking the circuit and no current is then passed
