Answer:
DILATION. Option A is correct.
Explanations:
Figures are said to be congruent when they are of the same shape and size.
When a figure is either reflected, rotated, or translated, what we are merely doing is changing the location of such figure in an xy-plane to another location. The geometry of both the image and the pre-image of the figure is not affected.
For dilation, this transformation involves changing the size of an image. For instance, if the coordinate of a figure say (x, y) is dilated by a factor of 2, the resulting coordinate of the image will be (2x, 2y). This shows that the resulting image is twice that of its pre-image.
Hence the transformations that may produce an image that is not congruent to the preimage is DILATION
