Correct answer: C
Concept
In blood-relation questions, replace each possessive phrase from the inside outward and compare the resulting people by generation and parentage. A shared father makes a woman and a man sister and brother.
Application
Let the speaker be W and the introduced person be Rakesh.
In ‘his brother’s father’, ‘his’ refers to Rakesh. Rakesh and his brother have the same father, so the phrase identifies Rakesh’s father.
The only son of W’s grandfather is W’s father under the intended family-tree convention.
Therefore, Rakesh’s father and W’s father are the same person. W and Rakesh are in the same generation and share a father.
Contrast
An aunt belongs to the parent’s generation, so that relation would place W one generation above Rakesh.
A mother is Rakesh’s female parent, which would also place W one generation above him.
A sister is a female sibling in the same generation who shares a parent with Rakesh.
A daughter is a female child, so that relation would place W one generation below Rakesh.
Cross-check
Drawing W’s grandfather above his only son gives that son as W’s father. Placing Rakesh under the same father makes W Rakesh’s sister. Thus, the woman is Rakesh’s sister.
