Answer: The correct answer is D) Point.
Point is represented by a dot, which has no width, length or height.
On the other hand, angle is a figure formed with the help of two rays, which share a common end point.
Line is a segment, which consists of two end points whereas ray is a part of line having only one end point. Therefore, angle, line, and ray all three have width or length.
