Geometry

Question Analysis:
This problem tests the ability to identify transformations based on coordinate changes.

Key Concept Explanation:
A reflection flips points across a line while preserving distances.

Step-by-Step Solution:
Compare original and transformed points:
x-coordinates are negated, but y-coordinates remain the same.
This suggests a reflection across the y-axis.

Option Analysis:
A) Rotation (Incorrect) – Rotation changes both x and y values differently.
B) Reflection (Correct) – Flipping across the y-axis matches the given transformation.
C) Translation ...
