When a ball is rising, the only force acting on the ball is the gravitational force corresponding to the mass of the ball.

The direction of the gravitational force acting on the ball is in vertically downward.

This gravitational force is the weight of the ball and the velocity of the ball decreases as moving towards the maximum height due to the action of force in the opposite direction of motion of the same ball.

Thus, the force acting on the ball when it reaches the half of its maximum height is its weight.

Hence, option a is the correct answer.
