A push of magnitude P acts on a box of weight W as shown in the figure. The push is directed at an angle θ below the horizontal, and the box remains a rest. The box rests on a horizontal surface that has some friction with the box. The normal force on the box due to the floor is equal to
A) W.
B) W + P.
C) W + P cos θ.
D) W + P sin θ.
E) W - P sin θ.
