Let’s analyze the relationships carefully:
1. C’s grandfather’s only daughter: This must be C’s mother (since if it were an aunt, she would have her own children who would be C’s cousins, not B) 2. B is the only child of C’s mother: This makes B and C siblings 3.
Therefore, C’s father is:
Father to C
Also father to B (since B and C are siblings)
But the question asks how C’s father is related to B 4.
The correct relationship is that C’s father is B’s father, but since this isn’t an option, we reconsider:
If we interpret ”C’s grandfather’s only daughter” as C’s paternal aunt (father’s sister):
Then B would be C’s cousin
Making C’s father the maternal uncle (mother’s brother) to B After careful reconsideration, the most accurate answer among the options is (A) Maternal uncle.
