Deduce Raman's Relation

This problem involves breaking down a complex family relationship statement step-by-step to identify the connection between the woman and Raman.

Grandfather's Daughter-in-law Interpretation

First, let's identify who "my grandfather's daughter-in-law" could be from Raman's perspective. This refers to the wife of Raman's grandfather's son. There are two main possibilities:

• Possibility 1: The son is Raman's father. In this case, the grandfather's daughter-in-law is Raman's father's wife, which is Raman's Mother.
• Possibility 2: The son is Raman's paternal uncle (father's brother). In this case, the grandfather's daughter-in-law is Raman's uncle's wife, who is Raman's Paternal Aunt.

Woman's Daughter-in-law Relation

Next, we determine who the woman is based on her relation to this identified person ("daughter-in-law of...").

• Following Possibility 1 (Grandfather's daughter-in-law = Raman's Mother):

  The woman is the "daughter-in-law of Raman's Mother". Raman's Mother's sons are Raman himself and his brother(s). Therefore, the woman could be Raman's wife or Raman's Brother's wife.

• Following Possibility 2 (Grandfather's daughter-in-law = Raman's Paternal Aunt):

  The woman is the "daughter-in-law of Raman's Paternal Aunt". Raman's Paternal Aunt's son is Raman's cousin brother. Therefore, the woman would be Raman's Cousin Brother's wife.

Relation to Raman Options

Now, let's compare these derived relationships with the given options:

• Paternal Aunt: This was an intermediate possibility, not the final relation to Raman.
• Sister: This relationship was not derived.
• Brother's wife: This matches the outcome from Possibility 1.
• Mother: While Mother was identified as a potential "grandfather's daughter-in-law", the puzzle asks who the *woman* is, described as a daughter-in-law of that person. If the woman were Raman's mother, she would be the daughter-in-law of Raman's grandmother, who is the grandfather's daughter-in-law. This scenario works, but typically these puzzles seek a relation distinct from the direct maternal line if other options fit more clearly via branching relationships. "Brother's wife" is a direct fit from Possibility 1.

Since "Brother's wife" is a direct match from a valid interpretation of the relationship chain and is provided as an option, it is the correct answer.
