Solution
The correct option is D Sister We solve these questions backwards. Rajesh's grandfather's only son would be his father or his maternal uncle (if he is his maternal grandfather). So the daughter of one's uncle and one's father in both cases would be ones sister. So Manju is Rajesh's sister.
