I believe the correct answer from the choices listed above is option B. The dilation from A (blue figure) to B (green figure) is an enlargement with a scale factor of 5/2.  In two similar geometric figures, the ratio of their corresponding sides is called the scale factor. Hope this answers the question.

Answer:

Option B

Step-by-step explanation:

In the figure attached we have to find the scale factor of dilation of figure A to figure B.

Since figure A is smaller than figure B, it concludes figure A has been enlarged to form figure B.

Now we have to find the scale factor of enlargement.

Scale factor =  [tex]\frac{\text{one side of the larger figure}}{\text{one side of the smaller figure}}[/tex]

=  [tex]\frac{5}{2}[/tex]

Therefore option B is the correct answer.
