Which shape is suitable to show a door in a drawing?

Rectangle

A door is commonly drawn as a tall shape with greater height than width. A rectangle represents this outline clearly because it has four straight sides and opposite sides that are parallel. Artists can add details such as a knob, panels, or a frame after drawing the basic shape. The question concerns the general outer form, not every possible special door design. Some doors may have curved tops or unusual decoration, but the simple rectangular form is the most familiar and suitable for elementary drawing.

Option A is correct because a rectangle matches the usual upright outline of a door. A circle and an oval are curved all around, so they do not show the common straight-sided frame. A triangle has a pointed form and is not the usual door outline. Therefore, the rectangle gives the clearest basic representation while leaving room for additional details inside it.
