Answer:

B. Dilation.

Explanation:

We are asked to find which transformation is not isometric.

We know that isometry preserves length.

We know that the length of a figure remains unchanged after rotation and dilation as they preserves length.

We also know that dilation either enlarges length or shrinks length of a figure, therefore, the correct choice is dilation.
