Nikhil, who is Raman's son, tells Isha, “Your mother Riya is my father's sister and my father is Suresh’s second child."
How is Suresh related to Isha?

Correct option is D

1. Nikhil, who is Raman's son, tells Isha that:

   • "Your mother, Riya, is my father's sister."This means Riya (Isha's mother) is Nikhil's father's sister, so Riya is Nikhil's aunt.

   • "My father is Suresh’s second child."This means Nikhil's father is the second child of Suresh, so Suresh is Nikhil's grandfather.

2. Since Nikhil’s father is the second child of Suresh, and Riya is Nikhil's aunt (meaning she is the sibling of Nikhil's father), Suresh is Isha's grandfather as well.

Conclusion:

Suresh is Isha's grandfather.

Correct answer:D. Grandfather
