Correct Answer:
Option C —
Sister-in-law
Here is the step-by-step breakdown of the relationships to see why:
Start with "my mother-in-law": This is the mother of Raj's wife.
Next, look at "the only son of my mother-in-law": The only son of Raj's mother-in-law would be his wife's brother (Raj's brother-in-law).
Finally, look at "the wife of the only son": This means the woman is the wife of Raj's brother-in-law.
Therefore, the woman is Raj's sister-in-law (specifically, his wife's brother's wife, or his brother-in-law's wife).
Let's re-read the options provided:
A) Sister
B) Wife
C) Sister-in-law
D) Cousin
The woman is Raj's Sister-in-law, which corresponds to option C.
(Self-correction: If Raj were a woman, "my mother-in-law's only son" would be her husband, and "the wife of my husband" wouldn't make sense in this context. Since Raj is a male name here, the mother-in-law's only son is his brother-in-law, making the woman his sister-in-law).
