Answer:
C. SAS
Explanation:
We already have the two pairs of sides that we know are congruent, but we also know that angles NTP and QTM are congruent because they are on opposite sides of the same intersection (I call them bowtie angles if that helps to understand). These two pairs of sides and the angles between them show that the triangles are congruent because of SAS (Side-Angle-Side Theorem).
Hope this helps :)
