Answer 1

Correct choice is (c) Isosceles triangle, irregular pentagon

Easy explanation: 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 H.P so its front view will be isosceles triangle and top view will be square.
