Best answer

Correct option (b) Horizontal component of the velocity

Explanation :

If a body is in the projectile motion, then its velocity can be resolved into horizontal and vertical components. And the body is subjected to the acceleration due to gravity (g), which is vertically downwards. Therefore horizontal component remains constant, while vertical component first decreases, becomes zero and then increases in the magnitude.
