Geometry

Question Analysis:
This question tests if students can distinguish between prisms and cylinders, especially when both have two bases.
The main focus is whether the bases are polygons and the sides are flat.

Key Concept Explanation:
Prisms:
Have polygonal bases (triangles, rectangles, etc.)
Have flat parallelogram lateral faces
Cylinders:
Have circular bases
One curved lateral surface

Step-by-Step Solution:
Bases = circles → not polygons
Side = curved, not flat → not a prism
