Acceleration due to gravity takes place every moment on earth whether you are throwing yourself up or else just diving into the pool. It is also indeed true that acceleration causes a change in velocity. But it happens that the change from a negative vector of velocity to positive one undergoes a period when the object/body literally has a Zero velocity for a very very short amount of time.

As at the highest point the velocity of body will be zero but the force on the body due to its weight i.e mg will act on it. And due to this force there will be acceleration due to gravity on that body

Explanation:
When a body is thrown upward, it undergoes a constant acceleration due to gravity in the opposite direction to its motion. As it reaches its maximum height, it momentarily stops before reversing its direction and falling back down.
Velocity at Maximum Height:
At the maximum height, the body's velocity is zero. This is because the body has come to a complete stop and is about to reverse its direction. The velocity is zero because the body is neither moving upward nor downward at that instant.
Acceleration at Maximum Height:
The acceleration at the maximum height is the acceleration due to gravity. This acceleration is always directed downward, towards the center of the Earth. It remains constant throughout the motion of the body. At the maximum height, the body experiences this acceleration, but its magnitude remains the same.
Acceleration is the Acceleration due to Gravity:
The acceleration due to gravity is the acceleration experienced by any object in free fall near the surface of the Earth. Its magnitude is approximately 9.8 m/s^2. At the maximum height, the body experiences this acceleration, even though its velocity is momentarily zero.
Reason for Answer:
Option D is the correct answer because at the maximum height of the body's motion, its velocity is zero (indicating a momentary stop) and its acceleration is the acceleration due to gravity (directed downward). This is a result of the body's upward motion being completely halted, and the influence of gravity on the body still present.
