Answer:
Corresponding angles of similar triangles are congruent.
The true statement is (c) one pair of congruent corresponding angles is sufficient to determine similar triangles
From the complete question (see attachment), we have:

∠NOP≅∠NML
This means that:
Angles NOP and NML are congruent
When the corresponding angles of similar triangles are congruent, then the triangles can be assumed to be similar.
