The image is congruent to the original square.

C. The image is similar to the original square.
Reason: Reflection is a rigid motion (preserves size and shape) and dilation with scale factor 2 preserves angles and multiplies all side lengths by 2. So the image has the same shape (square) with side length 10, making it similar but not congruent to the original.
