A Only I and II is true Correct Answer Incorrect Answer
B Only III is true Correct Answer Incorrect Answer
C Only II is true Correct Answer Incorrect Answer
D Either conclusion I or II follow, III and IV follow Correct Answer Incorrect Answer
E None of these Correct Answer Incorrect Answer

Solution

given statements:  K * D, D $ N, N % M, M © W After converting: K ≤ D , D > N , N = M , M ≥ W After combining: K ≤ D > N = M ≥ W Conclusion a → M % W  → M = W ( M ≥ W ) It will make a either case so both conclusion a and b is true Conclusion c → N @ D → N < D (D > N ) , it is true. Conclusion d → W @ N → W < N (N = M ≥ W), it is true.
