The gravitational force is independent of the intervening medium. In other words, the force between two masses remains the same whether they are in air, vacuum, water or separated by a brick wall.
Hence, (A) is an incorrect statement.
The gravitational force is a conservative force.
Hence, (B) is an incorrect statement.
The gravitational force obeys Newton's third law of motion. Thus, it forms action-reaction pair.
Hence, (C) is a correct statement.
The gravitational force is a central force. Hence, (D) is an incorrect statement.

Think about Gravitational Force. Which of the following statement is c...
Gravitational Force
Explanation:
The gravitational force is one of the fundamental forces in nature. It is the force of attraction between two objects due to their masses. The force is directly proportional to the product of the masses and inversely proportional to the square of the distance between them.
Action-Reaction Pair
According to Newton's third law of motion, for every action, there is an equal and opposite reaction. This principle applies to the gravitational force as well. When two objects exert gravitational forces on each other, they form an action-reaction pair. This means that if object A exerts a gravitational force on object B, then object B exerts an equal and opposite gravitational force on object A.
Non-Central Force
A non-central force is a force that does not act along the line connecting the centers of two objects. However, the gravitational force is a central force because it acts along the line connecting the centers of two objects. Therefore, option (d) is incorrect.
Conservative Force
A force is said to be conservative if the work done by the force in moving an object between two points does not depend on the path taken but only on the initial and final positions. The gravitational force is indeed a conservative force because the work done in moving an object against gravity only depends on the initial and final heights, and not on the path taken.
Intervening Medium
The gravitational force does not depend on the intervening medium. It acts between two objects regardless of the presence or absence of any medium between them. Therefore, option (a) is incorrect.
Conclusion
From the given options, option (c) is the correct answer. The gravitational force forms an action-reaction pair, obeying Newton's third law of motion.
