Answer 1

According to the question:

I. Rohan's father has three children.

So, Rohan has two siblings who can either brother or sister. Thus, no specific information regarding Rohan's brothers cannot be determined.

Here, statement I alone is not sufficient to answer the question.

II. Rohan has one sister.

Here, no information regarding Rohan's brothers cannot be determined.

Here, statement II alone is not sufficient to answer the question.

Combining statement I and II: Rohan's father has three children. Rohan has one sister.

So, Rohan is one brother.

Thus, Both statement I and statement II together are needed.

Hence, "Option 4" is the correct answer.
