Geometry

Question Analysis:
This reverse-engineering problem requires determining the rotation angle given initial and final positions.

Key Concept Explanation:
Rotation angle identification:
90° CW: (x, y)→(y, -x)
Test which rule matches the given transformation

Step-by-Step Solution:
Original point: (3, 4)
Transformed point: (4, -3)
Test rotation rules:
90° CW: (3, 4)→(4, -3) ✔️ Exact match

Option Analysis:
A) Correct transformation
B) Would give (-3, -4)
C) Would give (-4, 3)
