Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
When the molecules of a gas move only in one dimension, they move in both the directions. They do not move in one direction.Hence, the average velocity will be zero.
Thus, both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
