This question was addressed to me by my college director while I was bunking the class.

Enquiry is from Types of Perspective in chapter Oblique & Perspective Projection of Engineering Drawing

Answer 1

Right choice is (c) Distance point

For explanation I would say: The distance points are equidistant from the center of vision the distance of each from the centre of vision being equal to the distance of the station point from the picture plane the perspectives of all horizontal lines inclined at 45 degrees to the picture plane converge to a distance points on the horizon line.
