Pointing to a girl, Rohit says, "She is the daughter of the only son of my grandfather." Rohit is a male with no brothers. How is the girl related to Rohit?
The girl is Rohit's sister. The only son of Rohit's grandfather is Rohit's own father, so his daughter is Rohit's sister. She cannot be a cousin because the grandfather has no other son to be Rohit's uncle.

Explanation
The only son of Rohit's grandfather is Rohit's father (Rohit has no brothers and the grandfather has only one son, so this is his father). The daughter of Rohit's father is Rohit's sister. A cousin would require the girl's father to be Rohit's uncle, which is impossible as the grandfather has only one son.
