A heavy door of total width $W$ is attached to a wall by a hinge on its left side. A person pushes on the door with a constant force of magnitude $F$ at a point located a distance $D$ from the hinge. The force is applied at an angle $\theta$ with respect to the surface of the door, as shown in the top-down view below.

Which of the following is a correct expression for the magnitude of the torque exerted by the person on the door about the hinge?
