Who among the following is not considered consanguineous?

The individual who is not considered consanguineous is the wife. Consanguinity refers to the relationship between individuals who are related by blood. In the context of family relationships, a brother, a mother, and a father all share a biological connection, meaning they are directly related through genetics.

Conversely, a wife, in a typical context, does not share a blood relationship with her husband; rather, she is connected through marriage. While the bond of marriage creates a strong familial relationship, it does not contribute to consanguinity, which is strictly based on blood relations. Thus, the wife is the correct choice because she is not considered part of the consanguineous group.
