ANSWER
b. Dilation
Step-by-step explanation
A transformation is a change in the orientation or size of an object which results in an image that is similar in shape with the object.
First, let us define congruence.
Two shapes are said to be congruent if they have the same size and length.
All forms of transformation allow the image to be similar in shape and congruent to the object except dilation.
This is because dilation involves a change in the size of the object, causing the image to have bigger dimensions than the object.
The answer is Dilation. (Option B)
