Can anyone explain briefly?

What is the difference between effort and load?

I think option C is correct answer because he is asking the velocity ratio. So we should resolve the given force in to two components x-component is mgcosθ, y-components is mgsinθ. So the ratio is tanθ.

I think it should cosθ because weight is acting is down.

@Sourav Kundu.
You can be right but in this question angle is made b/w horizontal and inclination.
So cos(90°-x) = sin x.
So right answer is (A).

Didn't get any of the explanation. Can anyone explain it in a simpler way?

Option D is the correct answer.
V.R = 1/sin theta = cosec theta.
V.R = 1/sin theta = cosec theta.

I think option (B) because W and are make angle and weight is shown by cos.

@HARYHOR.
You replace distance by displacement.
