Question

- Cousin
- Niece
- Aunt
Show the answer and the worked solution
Correct answer: B. Cousin
Worked solution
- His father's sister is his paternal aunt.
- Her daughter is his cousin.
Answer: Cousin.
The idea
Aunt's or uncle's children are always cousins, whichever side of the family they come from.
Shortcut. 'The only sister of my father' is a paternal aunt, and an aunt's daughter is always a cousin — the word 'only' changes nothing here.
Common trap. "Niece" — confusing the father's sister with Rajan's own sister, whose daughter would be his niece.
