B. For every action there is no reaction
C. If an object exerts a force on a second object the second exerts an equal force in the opposite direction
D. Force is applied when there are two opposite objects

C. If an object exerts a force on a second object, the second exerts an equal force in the opposite direction.

Explanation:

I took the test lol

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
