ANSWER
Line segments AB and DE are congruent.
EXPLANATION
We are given that triangles ABC and DEF are congruent.
When two triangles are congruent, the corresponding sides and angles are congruent.
This means that:
[tex]\begin{gathered} and[tex]\begin{gathered} AB=DE \\ BC=EF \\ AC=DF \end{gathered}[/tex]Therefore, the only correct option is that line segments AB and DE are congruent.
