Husband’s mother
Brother’s wife
Husband’s sister Question ID : 4410091502090 Option 1 ID : 4410095932745 Option 2 ID : 4410095932747 Option 3 ID : 4410095932746 Option 4 ID : 4410095932744 Status : Answered Chosen Option : B
Husband’s mother
Break the expression into individual segments: Cp is the wife of Sj (Cp-Sj married), Sj is the brother of Qn, Qn is the daughter of Et, Et is the mother of Gy.
Break the expression into individual segments: Cp is the wife of Sj (Cp-Sj married), Sj is the brother of Qn, Qn is the daughter of Et, Et is the mother of Gy.
Analyze the expression Cp × Sj – Qn # Et + Gy
Cp × Sj means Cp is the wife of Sj. Sj – Qn means Sj is the brother of Qn. Qn # Et means Qn is the daughter of Et. Et + Gy means Et is the mother of Gy.
Establish the relationship chain
Since Sj is the brother of Qn and both are children of Et (Qn is daughter, Sj is son), Cp is the wife of Sj. Because Et is the parent of Sj, and Cp is married to Sj, Et is the mother of Cp's husband (Sj).
Final Conclusion
Et is the mother of Sj. Sj is the husband of Cp. Therefore, Et is the mother-in-law of Cp, or from the perspective of Et relative to Cp, Et is the husband's mother.
A: Son's wife describes Cp relative to Et, not Et relative to Cp. C: Brother's wife is incorrect because Sj is the husband, not a brother of Cp. D: Husband's sister is incorrect because Et is established as a parent (mother) of the husband.
B is correct because Et is the mother of Sj, who is the husband of Cp, making Et the husband's mother to Cp.
Always draw the gender of the individuals (use + for male, - for female) and note that in-law relationships are determined by marriage (indicated by × here).
