The correct answer is option A.

I think it is W sin 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.
And If theta is friction angle and force is applied parallel to base then the answer is C.

Yes, the Correct answer is tan(θ). Those who are saying cosθ' and sinθ, that is for inclined plane and not for horizontal surface. Here in question, it is only horizontal surface, so it's option C.

@Sandaz.
But we don't if the force applied is horizontal or at an angle to the surface.

@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).
