18. answer the question based on the information below ( im not sure if im right)

You are right!

Step-by-step explanation:

I'll go through why the others aren't right.

B:  BD/XY do not correspond to the similar sides of the two.  BC would need to be over WX and XY would need to be under CD

C:  The second proportion is reversed, you need to keep the shape that has its side in the numerator in the numerator and the one in the denominator int he denominator.

D:  Same as B.  You don't need to actually answer me, but maybe you can tell which sides correspond to those written.

Also let me know if you need any further explanation.
