We have to find the correct sequence of transformations that will result in similar, but not congruent, figures from the given choices.
Used keywords are "dilation", "reflection", "translation" and "Rotation".
Reflection happens about x or y axis or about some line but that results congruent figure.
Translation is basically shifting the figure up or down or left or right but that will still result in congruent figure.
Dilation is basically a stretch by some constant fixed factor in some direction. Which results in thik or thin figure than the original figure.
Rotation only moves figure clockwise or anticlockwise but figure is still congruent to the original figure.
Hence first choice "an image is dilated and reflected" is the only correct choice because dilation will not produce congruent figure.
