The plate is inclined to horizontal plane. Therefore the horizontal component of force will be Cosθ whereas the vertical component will become Sinθ.

Here velocity ratio inclined plane at θ/2 to horizontal.
Here sinθ/2=hypothesis.
Here sinθ/2=hypothesis.

A body is on an inclined plane means hypotension of right-angle triangle and effort applied upward means perpendicular of the triangle, velocity ratio is the distance by effort/distance by weight,
VR=P/h=h * sinθ/h = sinθ.
VR=P/h=h * sinθ/h = sinθ.

If x is the distance moved by the load on the inclined plane then the vertical distance moved by effort is also x. Now the velocity ratio is the distance moved by the effort to the distance moved by the load in the direction of effort.
That is x/x sin a = cosec a.
That is x/x sin a = cosec a.

If weight is resolved w sin θ acts parallel to plane.
Then,
P= w sinθ.
MA = W/P = 1/ sin θ = Cosecθ.
Then,
P= w sinθ.
MA = W/P = 1/ sin θ = Cosecθ.

I too agree, the correct answer is option D.

What is the velocity ratio?

The inclined weight should transform to the vertical and horizontal axis.
The inclined plane makes θ with the horizontal axis.
Then weight on x axis= wcosθ.
Weighht on y axis= wsinθ.
Velocity ratio= wsinθ/wcosθ.
= Tanθ.

It is Displacement/distance.
