Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Gases do not have free surface due to very less force of attraction between the molecules and the dispersed nature of gas molecules do not allow the gases to have a free surface.
For example- The gas molecules are equally distributed within the balloon without the formation of the surface.

Thus, Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Hence, the correct option is $A$
