Geometry

Question Analysis:
This problem tests the recognition of reflections in coordinate transformations.

Key Concept Explanation:
A reflection across the x-axis negates the y-coordinates while keeping the x-coordinates the same.

Step-by-Step Solution:
Compare original and transformed coordinates: (x, y) → (x, −y)
Since only the y-coordinates are negated, this confirms a reflection across the x-axis.

Option Analysis:
A) Rotation (Incorrect) – Would alter both x and y in a different way.
B) Reflection (Correct) – The negation of y-coordinates matches a reflection over the x-axis.
C) Translation (In...
