In a village of Bastar district in Madhya Pradesh, only two types of people live who belong to a tribal class. The first type is known as class A, while the other is known as class B. In that village, there is no other type of person except these two. The activities of both types of people are governed be prefectly patterned norms of social behaviour. Each person of the tribe has to obey the norms. They are rigid about this.
As far as marriage is concerned, the following norms are to be followed
(A). The people of class A cannot marry any other member of their own class, though they can marry members of class B.
(B). After being married, each male member ceases to be a member of that class in which he was born but automatically, he becomes the member of the other class to which his wife belongs.
(C). As far as females are concerned, they remain the members of their own class after being married.
(D). On his birth, the child automatically becomes the member of his mother's class.
(E). When any male member becomes widower or divorcee, then he again belongs to the group in which he was born.
(F). Nobody can marry more than one person according to social laws.

Which of the following marriages is not premissible according to the social laws ?

A. Any girl of class B marries his mother's brother.
B. Any widewer marries his wife's sister.
C. Any boy of class B marries his father's sister
D. Any widewer born in class A marries his brother's widow.
E. Any widow marries the former divorced husband or her daughter.
Answer: A . Any girl of class B marries his mother's brother.


A girl of class B will have mother born in class B and so the mother's brother will also belong to class B. Since people of any class cannot marry the members of their own class, so the condition in (a) is not permissible.
