Final answer:
The size stays the same, but the shape changes.
Step-by-step explanation:
The answer to the question is option B) The size stays the same, but the shape changes.
In mathematics, a transformation refers to a change in the position, size, or shape of a figure. Different transformations may include translations, rotations, reflections, or dilations.
When a shape undergoes a transformation, the size of the shape may remain the same, but the shape itself changes. For example, if a square is reflected across a line of symmetry, the size of the square remains the same, but its orientation changes.
