Geometry

Question Analysis
This question involves analyzing a geometric shape based on diagram.
The main focus is on identifying the sphere based on its key characteristics: constant radius, no edges, and no flat faces.

Key Concept Explanation
A sphere is defined as a set of all points in space that are equidistant from a fixed center point. It:
Has no flat faces, unlike cylinders or cones.
Has no edges or corners (vertices).
Is perfectly symmetrical in all directions.

Step-by-Step Solution
Option A (Cylinder): Has two flat circular faces and a curved surface → eliminate.
Option B (Cone): Has a flat base and one vertex → eliminate.
Option C (Sphere): Matches all given pr...
