Man Climbing a Rope

Assertion (A): When a man climbs the rope friction force acts in downward direction.
Reason (R): Friction force opposes relative motion or tendency of relative motion between two contact surfaces.
 
(1) Both (A) & (R) are true and the (R) is the correct explanation of the (A)
(2) Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(3) (A) is true but (R) is false
(4) Both (A) and (R) are false

Solution:

When a man climbs up, his hands exert a downward friction force on the rope. So (A) is true (referring to friction on the rope). (R) is the correct definition of friction and explains why this force acts.
