Explanation:

Dilation is a transformation that changes the size of a figure. When a figure undergoes dilation with a scale - factor, the size of the figure changes proportionally. The shape of the figure remains the same because the angles and the ratios of the side - lengths of similar figures (pre - image and image in dilation) are equal.

Answer:

For the question about dilation: d. The size changes proportionally while shape stays the same
