Pulling force making an angle to the horizontal is applied on

Question

Pulling force making an angle $θ$ to the horizontal is applied on a block of weight $W$ placed on a horizontal table. If the angle of friction is $α$ , then the magnitude of force is $α$ , then the magnitude of force required to move the body is equal to

\frac{W sin α}{g tan ( θ - α )}

\frac{W cos α}{cos ( θ - α )}

\frac{W sin α}{cos ( θ - α )}

\frac{W tan α}{sin ( θ - α )}
