On the diagram, notice that the segment LJ corresponds to the segment OM, JK corresponds to MN and KL corresponds to NO. Furthermore, those sides are congruent, which is enough to prove via SSS that:
From the options, two of them are wrong because they say that SAS is used to prove triangle congruence, which is not the case.
From the other two options, the order of the vertices on JLK is not in correspondence to OMN. Therefore, the correct answer is the third one.
