Prisms and pyramids are:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Polyhedrons
A polyhedron is a solid whose faces are all flat polygons, meeting in straight edges and corners. Every face of a prism (two end faces and rectangular side faces) and of a pyramid (a base and triangular side faces) is a polygon, so both are polyhedrons.
Why the other options are incorrect
Option (1) Polygons — Incorrect. A polygon is a flat closed figure; it only forms the faces of these solids.
Option (3) Cubes — Incorrect. A cube is one particular prism with six square faces; most prisms and no pyramid are cubes.
Option (4) Spherical shapes — Incorrect. A sphere has a curved surface with no flat faces or edges.
