Given:

Triangle ABC and triangle DEF are similar triangles.

To find:

The proportion that can be used to find the length of segment DE.

Solution:

We know that the corresponding sides of similar triangles are proportional.

Triangle ABC and triangle DEF are similar triangles. So, their corresponding sides must be proportional.

(AB)/(DE)=(BC)/(EF)=(AC)/(DF)

(AB)/(DE)=(BC)/(EF)

(4)/(DE)=(3)/(9)

(4)/(3)=(DE)/(9)

Therefore, the correct option is A.
