Question Analysis:
This question tests application of the 90° clockwise rotation rule about the origin.

Key Concept Explanation:
The rule for rotating a point 90° clockwise about the origin is:
Original point: (x, y)
After rotation: (y, -x)
This transformation swaps the coordinates and changes the sign of the new y-coordinate.

Step-by-Step Solution:
Identify original coordinates: (7, -2)
Apply 90° CW rotation rule:
New x-coordinate = original y-coordinate = -2
New y-coordinate = -original x-coordinate = -7
Final rotated point: (-2, -7)

Option Analysis:
A) Incorrect: Swapped coordinates but wrong signs
B) Correct: Follows (y, -x) rule perfectly
C) Incorrect: Reflects over origin instead of rotating
D) Incorrect: Partial transforma...
