I think the Correct option is A.

Option A is the correct answer.

The Answer should be Wsin(θ).

@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).

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

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.

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.

I think it is W sin θ.

The answer is A.
The minimum force required to slide a body of weight W on a rough horizontal plane is W sinϴ. A body of weight W is required to move up the rough inclined plane whose angle of inclination with the horizontal is α. The effort applied parallel to the plane is given by P = W (sinα + μ cosα).
