A is the brother of B, B is the brother of C. D is the father of A. Based on these three statements which of the following statements cannot be definitely true?
B is the brother of A
B is the son of D
D is the brother of A
C is the brother of A
Cannot be determined
A, B and C are siblings. A and B both are males but we don’t know about C either is male or female. So, we cannot say that C is the brother of A.
we dont know if c is a male or female but there is still a posibillity that c is the brother of a, therefore the answer should be d is the brother of a . as it is given that d is the father of a .
