Evaluate the following Assertion (A) and Reason (R) and choose the correct option.

Assertion (A): A body projected vertically upward from the ground takes the same time to rise to its highest point as it takes to return from the highest point to the ground, if air resistance is neglected.

Reason (R): During the complete motion, the acceleration is constant and vertically downward, so the upward and downward parts between the same two levels are symmetric in time.
