Family Tree Analysis
This problem requires constructing a family tree to determine the relationship between L and D.
Parents and Siblings of L
- L's Parents: L is the son of A and S.
- S's Sibling: S has one sibling, B.
D's Relation to Mother S
- B's Father: B is the only son of D. Thus, D is the father of B.
- D's Relation to S: Since S and B are siblings, D is also the parent of S.
- S's Gender: Given B is the only son, S must be the daughter of D.
- D's Role for L: D is the father of S (L's mother). Therefore, D is L's maternal grandfather.
L's Relation to D
- As D is L's maternal grandfather, L's relationship to D is that of a grandchild.
Aunt K's Role and Marriage
- K is identified as L's aunt and is married to B.
- An aunt is typically the sister of a parent. K cannot be S's sister, as S's only sibling is B.
- Therefore, K must be the sister of A (L's father), making her L's paternal aunt.
- The information that L's maternal uncle (B) is married to L's paternal aunt (K) is consistent but does not alter the established relationship between L and D.
Final L-D Relationship
Based on the analysis, L is the grandchild and D is the maternal grandfather.
This corresponds to the option: Grandchild and Maternal Grandfather.
