Geometry

Question Analysis:
This question evaluates precise correspondence in congruent triangle naming.

Key Concept Explanation:
Naming order dictates correspondence: M↔P, N↔Q, O↔R.

Step-by-Step Solution:
Analyze naming:
M↔P, N↔Q, O↔R.
Thus:
NO ↔ QR (correct, C).
MN ↔ PQ (not PR, A is wrong).
∠M ↔ ∠P (not ∠Q, B is wrong).
∠O ↔ ∠R (not ∠P, D is wrong).

Option Analysis:
C) Only correct correspondence...
