Given below are two statements:
 Assertion (A): The work done on bringing a body down from the top to the base along a frictionless inclined plane is the same as the work done in bringing it down the vertical side. Reason (R): The gravitational force on the body along the inclined plane is the same as that along the vertical side.

 1 Both (A) and (R) are true and (R) is the correct explanation of (A). 2 Both (A) and (R) are true but (R) is not the correct explanation of (A). 3 (A) is true but (R) is false. 4 Both (A) and (R) are false.
