Answer:
It is the 1st answer.
Step-by-step explanation:
In order to prove its a parallelogram, you need to prove that both pairs of opposite sides are congruent. Seeing how if you draw a line through the middle of the parallelogram it creates to congruent triangles (Im guessing thats what the question is implying), you can prove that PN ≅ MQ and that PQ ≅ NM, therefore proving that both pairs of opposite sides are congruent
PS. Good luck with proofs, they suck
