I got this question in exam.

This intriguing question originated from Development of Surfaces topic in section Development of Surfaces, Isometric Projections, Perspective Projections & Transformation of Projections of Civil Engineering Drawing

Answer 1

Right choice is (a) objects having isometric lines

Explanation: Isometric lines – Designating a method of projection (isometric projection) in which a three-dimensional object is represented by a drawing (isometric drawing) having the horizontal edges of the object drawn usually at a 30° angle and all verticals projected perpendicularly from a horizontal base, all lines being drawn to scale.
