Given:

The figure of two triangles.

To find:

The scale factor.

Solution:

We know that,

$\text{Scale factor}=\frac{\text{Side of Image}}{\text{Corresponding side of original figure}}$

In the given figure,

$\text{Scale factor}=(5(2))/(5)$

$\text{Scale factor}=2$

The scale factor is 2. Therefore, the correct option is B.
