Velocity ratio=height of inclined plane/length of the inclined plane,
= h/l,
= sin(θ).
= h/l,
= sin(θ).

distance moved by effort= hyp.sinθ
distance moved by load= hyp
V.R= distance moved by effort/distance moved by load
V.R= sinθ.
distance moved by load= hyp
V.R= distance moved by effort/distance moved by load
V.R= sinθ.

A is the right answer. I agree.

Due to the effort the block moves up the inclined plane.
Due to the effort the velocity created along the plane is v.
Velocity created due to vertical effort is v siny.
Therefore VR {vertical effort to effort} = siny.
Due to the effort the velocity created along the plane is v.
Velocity created due to vertical effort is v siny.
Therefore VR {vertical effort to effort} = siny.

What is velocity ratio here?

I think the correct answer is tan θ.

Suppose distance moved by a load on an inclined plane is x meter. So, the distance moved by effort is x sin θ. Now velocity ratio is equal to x sin θ upon x so hear sin θ is the right answer.

Velocity ratio (Vr) = displacement by effort / displacement by force.
While pulling a block on an inclined plane, there is a vertical effort made by man to pull it through the pulley (which is a vertical plane, opposite to angle) By this force the block moves some displacement (which is on an inclined plane).
