Pointing to a photograph, Arjun said, "She is the mother of my son's wife's daughter." How is Arjun related to the lady in the photograph?

Introduction / Context:

This question uses a chain of relationships that moves from Arjun to his son, then to his son's wife, and then to that wife's daughter. It is a good example of how exams test the ability to understand in-law relationships and generational levels, especially the role of a daughter-in-law.

Given Data / Assumptions:

• Arjun is speaking.
• He says about a lady in a photograph: "She is the mother of my son's wife's daughter."
• Arjun has a son.
• The son is married, so "my son's wife" is Arjun's daughter-in-law.
• "My son's wife's daughter" is the child of Arjun's daughter-in-law (and of his son).
• We assume standard family structure.

Concept / Approach:

We decode the phrase from the inside out. First identify "my son's wife" as the daughter-in-law. Her daughter is Arjun's granddaughter. The lady in the photograph is the mother of that granddaughter, which logically makes her the daughter-in-law herself. Once recognized, Arjun's relationship to her is simple: she is his son's wife and thus his daughter-in-law.

Step-by-Step Solution:

Verification / Alternative check:

Label the people: Arjun = A, his son = S, S's wife = D, and their daughter = G. G is "my son's wife's daughter" from A's perspective. The mother of G is D. So the lady in the photograph is D. From A's point of view, D is his daughter-in-law. This matches the reasoning and confirms the answer.

Why Other Options Are Wrong:

Arjun is not her uncle or cousin; those terms describe collateral relations, not relations created by his son's marriage.

"None of these" is incorrect because "daughter-in-law" fits perfectly and is explicitly represented among the options.

Common Pitfalls:

Some examinees get lost in the repeated use of "son" and "wife" and mistakenly think that the lady is the granddaughter or some other relative. Always identify the inner link "my son's wife" first, label that person, and then carefully see who her daughter is and who that daughter's mother must be. This step-by-step approach avoids confusion.

Final Answer:

Arjun is the lady's father-in-law, so she is his daughter-in-law.
