Answer:
Option C. 3
Explanation:
The picture of the question in the attached figure
we know that
A dilation is a non rigid transformation that produce similar figures
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
In this problem the pink trapezoid and the blue trapezoid are similar figures
so
The ratio of the greater base of the blue trapezoid to the greater base of the pink trapezoid is equal to the scale factor
