Answer:
There should be three possible answers to this problem. (See below)
SAS, ASA, and AAS according to which congruent sides and angles one considers.
Explanation:
For what I can tell, there are three possible answers to this problems from the options given to conclude that triangles MNK and KLM are congruent. This is because, apart from having internal equal alternate internal angles between two sets of parallel lines, we also have TWO equal sides (one is the side KM common to both triangles and the other is the marked ML = NK).
I illustrate such three possible answers in the attached image.
