At a point of maximum height, the derivative of displacement i.e. velocity is zero but as the gravitational acceleration is equal at all near points to the surface of earth, acceleration at maximum height is still equal to g.

Explanation:
When an object is thrown upwards, it moves upwards until it reaches its maximum height. At this point, the velocity of the object becomes zero. This is because the object has stopped moving upwards and is about to start falling down due to gravity.
At the point of maximum height, the acceleration of the object is equal to the acceleration due to gravity (g). This is because the only force acting on the object is the force of gravity, which is pulling it downwards.
Therefore, the correct answer is option B - the acceleration at the point of maximum height is g.
To summarize:
- When an object is thrown upwards, it moves upwards until it reaches its maximum height.
- At the point of maximum height, the velocity of the object becomes zero.
- The only force acting on the object at this point is the force of gravity, which is pulling it downwards.
- Therefore, the acceleration of the object at the point of maximum height is equal to the acceleration due to gravity (g).

Because of laws of gravational force acting on a body and acceration due to body falls downwards that's why option b is correct
