Read the information given below and answer the question that follows. (i)…

Concept: In a blood-relation family-tree puzzle, first fix each person's generation and then pin down every parent-child, marriage, and sibling link directly from the clues (words like father-of, daughter-in-law-of, sister-of) before answering the question asked.

1. Clue (iii) makes Pratap the father of Prashant and the grandfather of two grand-daughters, so Pratap sits in the first (eldest) generation.

2. Clue (vi) places Abha and Ritu as grand-daughters of one of the housewives; matching this with clue (iii) makes Abha and Ritu the two grand-daughters of Pratap, in the third generation.

3. Since both wives have exactly two children each, Pratap's wife's two children are Prashant and Pooja, so from clue (iv) — Pooja, a doctor, being the sister of a teacher — Prashant is that teacher and Pooja is his sister, both in the second generation.

4. Clue (v) names Sumiti as the daughter-in-law who is married to a teacher; since Prashant is the teacher, Sumiti is Prashant's wife, forming the second married couple, and their two children are Abha and Ritu.

5. Clue (iii) names Pratap's wife as the mother of his children; matching her identity to the person named in clue (v) as Prashant's mother confirms she is Madhu, making Pratap and Madhu the first-generation married couple.

The family therefore has two married couples — Pratap with Madhu, and Prashant with Sumiti — while every other pairing links people across generations or within the same generation as siblings or children, not as spouses.

• Prashant and Pooja are Madhu's two children, so they are siblings, not spouses.

• Pratap and Ritu are two generations apart — grandfather and grand-daughter — not spouses.

• Prashant and Abha are parent and child, not spouses.

So, Pratap and Madhu are the married couple asked for in the question.
