Verified answer

Answer:

B. Force

Explanation:

It is force because the greater the force exerted on the object, the faster and more prolonged the range/distance of its trajectory. Also, you already know that force is equal to mass times the acceleration. So, it also considers the mass of the object and the influence of gravity.

The angle, probably the angle at which the projectile launches, may also be an answer. Because the closer the angle to 90 degrees, the shorter the distance of the object's travel.

But, I'll still stick to letter B as the correct answer.
