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.

Weight w acts downward so that to move weight w we should only give force equals to frictional force. It will be wtanthita.

F equals to uR and u equals to tan of angle of friction. And R equals to W for horizontal plane. On this perspective, it should be the option (C).
