Geometry

Question Analysis:
This question combines multiple diagonal properties.
The main focus is identifying the shape that satisfies all three conditions simultaneously.

Key Concept Explanation:
Rhombus: Diagonals are perpendicular and bisect but not equal.
Rectangle: Diagonals are equal and bisect but not perpendicular.
Square: Only shape where diagonals meet all three criteria.

Step-by-Step Solution:
Option A: Fails the "equal diagonals" condition.
Option B: Fails the "perpendicular" condition.
Option C: Correct. Squares inherit properties from both rhombuses and ...
