Question
Assertion (A): The position of the centre of gravity of a body remains unchanged even when the body is deformed.
Reason (R): The centre of gravity of a freely suspended body always lies vertically below the point of suspension.
Options
Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion.
Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion.
Assertion (A) is false, but Reason (R) is true.

Solution
Assertion (A) is false, but Reason (R) is true.
Explanation:
Deforming a body can change the distribution of its mass and therefore change the position of its centre of gravity; Assertion (A) is false. When a body is freely suspended and at rest, its centre of gravity lies vertically below the point of suspension, so Reason (R) is true.
