व्याख्या:
We need to find the relation of E to B given 5 members: A, B, C, D, E. Let us test Statement-1, Statement-3, and Statement-4: - Statement-1: A and B are a married couple (so one is husband, one is wife). - Statement-4: A and C are sisters. (This means A is female, and C is female, and since A and B are a married couple, B must be male, i.e., the husband of A). - Statement-2: D is the father of C. (Since A and C are sisters, D is also the father of A). - Statement-3: E is D's son. (Since A and C are daughters of D, and E is D's son, E is the brother of A and C). Now, let's determine the relation of E to B: - A and B are husband and wife (B is husband, A is wife). - E is the brother of A. - Therefore, E is the brother-in-law of B. Thus, Statements 1, 3, and 4 (along with Statement 2 as implied, but let's check which option combines them: Option (b) states 'Statement-1, Statement-3 and Statement-4 are sufficient to answer the Question'). Wait, let's verify if Statement 2 is even needed with 1, 3, 4: With 1 (A, B married), 3 (E is D's son), 4 (A, C sisters), do we know D? Without Statement 2, we don't know who D is! Wait, let's check Option (c): 'All four statements together are sufficient to answer the Question.' Let's re-verify: Statement 2 says D is the father of C. Combined with Statement 4 (A and C are sisters), D is the father of A and C. Combined with Statement 3 (E is D's son), E is the brother of A. Combined with Statement 1 (A and B are married couple), B is married to A, making E the brother-in-law of B. Hence, all four statements together are necessary and sufficient. Option (c) is correct.
