Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The force on the projectile is the gravitational force which acts only in the vertically downward direction. Now the work done on the horizontal component of velocity will be zero since they are perpendicular to each other. So, its velocity remains constant.
