Answer
Correct Answer: Daughter
Explanation
Introduction / Context:We first identify who the woman is to the man and then infer her relation to the man's maternal grandmother.
Given Data / Assumptions:
- "Your brother's only sister is my mother." If the woman's brother has only one sister, and that person is the man's mother, then the woman is that only sister ⇒ the man's mother.
Concept / Approach:If the woman is the man's mother, her relation to the man's maternal grandmother (the woman's own mother) is simply "daughter."
Step-by-Step Solution:
Woman's brother → only sister = woman (unique).Given "only sister is my mother" ⇒ woman = man's mother.Man's maternal grandmother = woman's mother ⇒ woman is her daughter.Verification / Alternative check:Family tree labels confirm: GM (maternal) → Mother (woman) → Man. Relation asked is Daughter.
Why Other Options Are Wrong:Mother/sister/niece/granddaughter misplace generations relative to the grandmother.
Common Pitfalls:Assuming multiple sisters; the statement specifies "only sister."
Final Answer:Daughter
