Answer»

The CORRECT answer is (d) Orthographic projection

To explain: In the above starting 3 methods, these REPRESENTS the object by a PICTORIAL VIEW as EYES see it. In these methods of projection a 3-d object is represented on a projection plane by one view only. While in the orthographic projection an object is represented by 2 or 3 views on the mutual perpendicular projection plane. Each projection view represents 2-D of an object.
