Map the generation hierarchy: D and E are children of B; since A is the brother of B, A is the maternal/paternal uncle of D and E.
Establish the relationship chain
D is the brother of E, and E is the daughter of B, which means B is the parent of both D and E.
Identify the uncle relationship
A is the brother of B. Since B is the parent of D, the brother of B (which is A) is the maternal or paternal uncle of D.
B: B is the parent of D, not the uncle. C: C is the sister of A, making her the aunt of D. D: D is the person for whom we are finding the uncle, not the uncle himself.
A is correct because A is the brother of B, who is the parent of D, thereby making A the uncle of D.
In blood relation problems, always establish the parent-child relationship first before identifying siblings or extended family members to avoid confusion.
