Assertion (A): A person walking on a horizontal road with a load on his head does no
work.
Reason (R): No work is said to be done, if directions of force and displacement of
load are perpendicular to each other.
Select the most appropriate answer from the options given below:
a) Both A and R are true and R is the correct explanation of A
b) Both A and R are true but R is not the correct explanation of A.
c) A is true but R is false.
d) A is false and R is also false.
