It is easier to draw up a wooden block along an inclined plane than to haul it vertically, principally because

AThe friction is reduced

BThe mass becomes smaller

COnly a part of the weight has to be overcome

D‘g’ becomes smaller

Solution

(c)Opposing force in vertical pulling $= mg$
But opposing force on an inclined plane is $mg\, sin \theta$, which is less than $mg$.
