Answer:

D. ∠E ≅ ∠N

Explanation:

The pair of sides meet at vertex E in ∆DEF and at vertex N in ∆MNO. Since the sides that make up angles E and N are shown congruent, it is sufficient to show ...

∠E ≅ ∠N

Then the SAS congruence postulate can be claimed.

Additional comment

The alternative is to show DF ≅ MO. That would allow you to claim SSS congruence. That is not an answer choice.
