Question Analysis
This question tests the fundamental property of spheres: all are similar regardless of size.

Key Concept Explanation
All spheres are similar because:
Identical shape (no edges/angles to compare).
Only radius varies, maintaining uniform scaling.

Step-by-Step Solution
Option A: 14 cm (scale factor = 2).
Option B: 7 cm (scale factor = 1, congruent).
Option C: 3.5 cm (scale factor = 0.5).
All are scaled versions of Spher...
