Shown in the image is a door with marked hinges and four labeled doorknobs. $A$ is closest to the hinges. $B$ and $D$ are equidistant horizontally from the hinges, but $D$ is located higher on the door. $C$ is furthest from the hinges.
An equal pulling force, $F$, is applied to each door knob perpendicular to the hinge to doorknob line.
Which of the following correctly ranks the applied torque to each doorknob from greatest torque to least torque (magnitude only)?
