Option B: 
Explanation:
The polygons are similar because in
, the measure of ∠R=32°
Also, in
, the measure of ∠U=32°
Now, we shall find the scale factor,
Since,
, then the sides are proportional which is given by,

Substituting the values of RS and UV from the figure, we get,

Simplifying, we have,

Thus, the scale factor is 
Hence, Option B is the correct answer.
