A rotation is a transformation that turns a figure around a fixed - point. The shape and size of the figure remain the same, only its orientation changes.

Step2: Analyze Option A

Option A shows a reflection (a flip) of the original triangle over a vertical line.

Step3: Analyze Option B

Option B shows a rotation of the original triangle. The triangle has been turned around a point, and its shape and size are unchanged, but its orientation is different.

Step4: Analyze Option C

Option C shows a translation (a slide) of the original triangle. The triangle has moved to a different position without any rotation or reflection.
