Answer: a parallelogram with a right angle.

All other descriptions mention quadrilaterals, diagonals, and angles which pertain to rectangles. However, a parallelogram does not guarantee the figure is a rectangle, and this description only mentions one right angle, whereas rectangles have four right angles.
