Option 1: Both the statements are individually true and Statement II is the correct explanation of Statement I.

This option is not correct as it contradicts with the correct answer. The correct answer states that Statement I is true but Statement II is false, so this option cannot be the correct explanation.

Option 2: Both the statements are individually true but Statement II is not the correct explanation of Statement I.

This is the correct answer. Statement I is true because a body moving in a circular path experiences a force towards the center of the circle, called the centripetal force. However, Statement II is false because the centripetal force does not do work to keep the body rotating in the circular path. This is because the centripetal force is always perpendicular to the displacement of the body, so no work is done.

Option 3: Statement I is true but Statement II is false.

This is the correct answer. Statement I is true because a body moving in a circular path experiences a force towards the center of the circle, called the centripetal force. However, Statement II is false because the centripetal force does not do work to keep the body rotating in the circular path. This is because the centripetal force is always perpendicular to the displacement of
