Blood relation:

In blood relation reasoning questions, a certain relationship is given between people and we have to find the relationship of the remaining person with the other. In this question, it is given that,

• A is B's Brother
• A is C's Brother

Now we have to find how B is related to C.

We know that A is both B and C's brother, which means A, B, and C are cousins or siblings. However, we don't know whether B is C's brother or sister, as the gender of B is not given.

Hence, B's sex​ is the minimum information needed to find the relation between B and C,
