Read the following information carefully and answer the question given below…

Concept: In blood-relation puzzles, decode each clue into a family-tree edge one at a time — a person described as the "brother/sister of X" shares X's own parents (same generation as X), while being the "son/daughter of Y" (or a sibling of that child) places them as Y's own child, one full generation below Y.

Application:

1. A and B are a married couple with A the male member, so A is the husband and B is the wife.

2. C is described as the brother of A, so C shares A's parents and stands in the same generation as A.

3. D is the only son of C, so D is C's own child, one generation below C.

4. E is the sister of D; since D's parent is C, E shares that same parent, so E is also C's own child.

5. B is the daughter-in-law of F, whose husband has died, so F is the widowed parent of B's husband A (and hence also the mother of C).

Cross-check: Testing each option against the derived tree — a sister of C would need to share C's own parents, but E's parent is C himself, so that is ruled out; a cousin would need E's parent to be a sibling of C, but E's parent is C directly; an aunt would need E to sit one generation above C, a sibling of C's parent, but E sits one generation below C. Only one relationship fits a same-generation-below child of C.

Result: E is the daughter of C.
