@All.
Here all are making a mistake with using "Force" and "Work". The work is the same in this question. Since you need less Force to push/pull the object on a slope (without friction applied) than vertically. But the distance is more on the Slope than vertically. Thus W = F x s -> W1 = W2.

The work done is the same but the rate of doing work is greater on lifting.

According to me, C is the correct answer. Because no more or less work is done if the displacement is the same in both the case.
