Pyramid here have -

5 vertices and 8 edges

Which is only possible in Pyramid of 4 triangles with a square base

Hence 4 sides of triangle + 1 side of Square = 5 faces

Option B.

pyramid is a conical structure resting on a rectangular surface.
hence it should be 1 square surface at the bottom and 4 triangular surface on top of t.
Thus total 5 faces.

I believe base of pyramid must be square in above situation and not rectangular, could you please review and advise.
