Correct answer: D

Here is a clean copy-paste explanation for the solution section:

Explanation:
Given postfix expression:
M N O + P / Q R S T / +

Step 1: N O + → (N + O)
Step 2: M (N + O) → M(N + O)
Step 3: (M(N + O)) / P → (M(N + O)) / P
Step 4: S T / → (S / T)
Step 5: R + (S / T) → (R + S/T)
Step 6: Q (R + S/T) → Q(R + S/T)
Step 7: Final subtraction →

((M*(N+O))/P) − (Q*(R+(S/T)))

Final Answer: ((M*(N+O))/P) − (Q*(R+(S/T)))
