Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
At absolute zero (0 $K$ ) temperature, the thermal motion of gas molecules becomes negligible and hence their $K E$ and vapour pressure also reduce to zero.

So, both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
