If Neena says, "Anita`s father Raman is the only son of my father-in-law Mahipal", then hoe is Bindu, who is the sister of Anita, related to Mahipal ?
Answer: A. None of these
Only son of Neena's father--in-law Mahipal -- Neena's husband.
So, Raman is Neena's husband and Anita and Bindu are his daughters.
Thus, Bindu is the grand daughter of Mahipal.
