The image is missing (however it's not necessary to solve the problem).
The correct answer is A) decreases, because the gravitational force is inversely proportional to the square of the distance. In fact, the magnitude of the gravitational force between two object of mass M and m, at a distance d one from each other, is
where G is the gravitational constant. As can be seen from the formula, if the distance d between the two object increases, the intensity of the force decreases.

Answer: 2.92 s
Explanation:
Given
Mass of ball is
The initial velocity of the ball is
Velocity after the rebound is
Force during the contact is
We know, change in momentum is Impulse
Thus, the force is applied for 2.92 s
