I had been asked this question by my school principal while I was bunking the class.

My question is taken from Definitions and Methods of Perspective Projections topic in chapter Oblique & Perspective Projection of Engineering Drawing

Answer 1

The correct option is (d) station line

Easy explanation: In perspective projection, the line in which the horizon plane intersects the picture plane is called horizon line. It is parallel to ground line. And the point in which the perpendicular axis pierces the picture plane and lies on horizon line is called center of vision.
