Geometry

Question Analysis:
This problem combines rotation and translation.
We need to correctly apply the rules for each in the given order.

Key Concept Explanation:
Rotation (90° counterclockwise): Swaps x and y and makes the new x negative.
Translation (2 units down): Subtracts 2 from the y-coordinate.

Step - by - Step Solution:
Rotation: For P(x, y), after 90° counterclockwise rotation, it becomes P'(-y, x).
Translation: Translating P'(-y, x) 2 units down gives P''(-y, x - 2).

Option Analysis:
Option A: Correct.
Option B: Applies translation to the wrong coordinate.
Option C: Incorrect sign...
