Solution

The correct option is D is not acted upon by any horizontal forces
When a batsman hits a cricket ball in air , it follows the projectile motion . As there is no acceleration (so , no force ) in horizontal direction , therefore horizontal speed remains constant through the whole journey . Whereas vertical speed changes due to gravitational acceleration .
