The question was posed to me in an internship interview.

Enquiry is from Projections of Solids with Axis Inclined to Vertical Plane and Parallel to Horizontal Plane topic in section Projection of Solids of Engineering Drawing

Answer 1

Right option is (c) Irregular pentagon, isosceles triangle

The explanation is: Given a square pyramid which means the projection to its base gives square shape and other orthographic views give triangle. Here given is pyramid whose axis is inclined to V.P so its front view will be irregular pentagon and top view will be isosceles triangle.
