Question: How is Tanya related to the man in the photograph ?
Statements:
- Man in the photograph is the only son of Tanya's grandfather.
- The man in the photograph has no brothers or sisters and his father is Tanya's grandfather.
Answer: Option
Explanation:
From I, we conclude that the man is the only son of Tanya's grandfather i.e. he is Tanya's father or Tanya is the man's daughter.
From II, we conclude that the man's father is Tanya's grandfather. Since the man has no brothers or sisters, so he is Tanya's father or Tanya is the man's daughter.

From 1: The man in the photograph is the only son of Tanya's grandfather.
It means he had only one son, because he said only son, (that means no daughters and no sons, rather than one son) and he said TANYA'S GRANDFATHER, which means granddaughter of his SON. IT means Tanya is the daughter of her grandfather"s son.
So, only one statement can be correct.

First of all, the son of Tanya's grandfather maybe her maternal uncle or her father.
Correct me, if I am wrong.

Statement I: “Man in the photograph is the only son of Tanya’s grandfather.”
This could mean the man is either Tanya’s father or her paternal uncle.
Statement II: “The man in the photograph has no brothers or sisters and his father is Tanya’s grandfather.”
This clarifies that the man has no siblings, which means he cannot be Tanya’s paternal uncle (since he would need to have a brother, Tanya’s father).
Given this, Statement II alone is indeed sufficient to determine that the man in the photograph is Tanya’s father, as he has no siblings and his father is Tanya’s grandfather.
So, the correct option should be B) II alone is sufficient while I alone is not sufficient.
This could mean the man is either Tanya’s father or her paternal uncle.

In case some guys are saying that only son doesn't mean Tanya's grandfather has no daughter, yes it is possible but the old man would be maternal grandfather not the grandfather with respect to Tanya.
As per question option c is correct.

Definitely C.
If you look at the explanation, both answers end in this phrase, "he is Tanya's father or Tanya is the man's daughter".

The answer should have been C. Both statements convey the man as Tanya's father. The gender of Tanya is irrelevant to the answer.
