Geometry

Question Analysis:
This question involves identifying the fixed point around which a rotation occurs.
The main focus is on understanding the center of rotation, especially when the rotation is "about the origin."

Key Concept Explanation:
In coordinate geometry, when we say "rotation about the origin," we refer to a rotation with center at (0, 0).
All points rotate around this fixed point.

Step-by-Step Solution:
By definition, “about the origin” means the center is at (0, 0).
Therefore, the correct answer is A.

Option Analysis:
A. ✅ (Correct) — The definition of "rotation about the origin".
B. ❌ Just another point, not relevan...
