@All.
Actually, the question is not properly defined.
When a horizontal force is applied to the block the W tan (theta) is the right answer.
But when we apply a force that is inclined to the horizontal instead of a horizontal force then the minimum force is Wsin (θ).

If theta is the angle at which force is applied then the answer is A.
And If theta is friction angle and force is applied parallel to base then the answer is C.

The answer is wsinθ
W tanθ. Is for moving body upward on an inclined plane by neglecting the friction?

Here it is a miskate in symbol, instead of θ it must be φ.
P=uR=tan φW.
P=uR=tan φW.
