Correct answer: (A) Wife's mother's father
S is father of D, D is brother of R (so S is also R's father), R is mother of Y, and Y is wife of H. Since S is R's father and R is Y's mother, S is Y's maternal grandfather, making S related to H (Y's husband) as 'wife's mother's father'.

सही उत्तर: (A) एक
S, D का पिता है, D, R का भाई है (अतः S, R का भी पिता है), R, Y की माता है, और Y, H की पत्नी है। चूँकि S, R का पिता है और R, Y की माता है, S, Y का नाना है, जिससे S, H (Y का पति) से 'पत्नी की माता के पिता' के रूप में संबंधित है।
