Answer: The correct option is
(B) [tex]\dfrac{RS}{WX}=\dfrac{ST}{XY}=\dfrac{TR}{YW}.[/tex]
Step-by-step explanation: Given that triangle RST is similar to triangle WXY in the figure.
We are to select the correct proportionality statement for the ratio of the sides of the triangles.
From the figure, we note that the corresponding pairs of vertices of ΔRST and ΔWXY are
(R, W), (S, X) and (T, V).
Therefore, the proportionality statement for the ratio of the sides of the triangles is
[tex]\dfrac{RS}{WX}=\dfrac{ST}{XY}=\dfrac{TR}{YW}.[/tex]
Thus, the correct option is (B).
