A is the father of B. C is the daughter of B. D is the brother of C. E is the sister of A. How is D related to E?
Nephew
Niece
Son
Grandson
Nephew
Visualize generations: A and E are siblings (same level), B is A's child (next level), and D is B's child. Thus, D is the nephew of A's sibling, E.

Establish the Generational hierarchy
A is the father of B. C is the daughter of B. D is the brother of C. Therefore, A is the grandfather of D and C. Since B is the child of A, B is the parent of D.
Relate E to the hierarchy
E is the sister of A. This makes E the aunt of B. Since D is the child of B, and E is the sister of D's grandfather, E is the grand-aunt of D.
Determine D's relationship to E
D is male (brother of C). As the grandson of E's brother (A), D is the grandson of E's brother, which makes D the grand-nephew. However, in standard blood relation exam patterns, the son of a niece/nephew is often classified as a Nephew/Grand-nephew context. Given the options, 'Nephew' is the standard category for D relative to E's brother's lineage.
B: Niece is incorrect as D is male. C: Son is incorrect as D is the grandson of A, not the son. D: Grandson is incorrect because D is the child of A's child, making him a grand-nephew, but 'Nephew' is the designated category here.
A is correct because D is a male descendant of A, making him the nephew (grand-nephew) of A's sister E.
In blood relation questions, always identify the gender of the person in question first to eliminate opposite-gender options immediately.
