Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Manoj is the brother-in-law of Jatin
The husband of one’s sister is one’s brother-in-law; the wife of one’s son is one’s daughter-in-law.
Isha and Jatin are the two children of Gopal and Hansa, so Isha is Jatin’s sister
Kirti is the wife of Jatin, so she is the daughter-in-law of Gopal and Hansa
Lakshay is the son of Jatin and Kirti, so his father’s mother is Hansa
Manoj is the husband of Isha, Jatin’s sister
