Answer: D) directed downward.

Explanation:

We know that the constant acceleration of $9.87ms^{-2}$ of every-thing is always DIRECT DOWNWARDS because of the to the influence of the gravity of the Earth.

This motion is denoted as free fall motion , where the acceleration due to the gravity is constant $9.87ms^{-2}$ .

∴ A ball tossed vertically upward rises, reaches its highest point, and then falls back to its starting point. During this time the acceleration of the ball is always directed downward.

Hence, the correct answer is D) directed downward..
