Review the information by clicking the link above and answer the following question.

If E is B's grandfather, then which of the following must be true?

1. E is B's aunt.
2. Z is C's son.
3. A is Z's brother.
4. D is F's husband.
5. C is B's aunt.

There is only one available grandfather-grandchild relationship: E must be Z's father and B his daughter. If B is female, then A is male and must be Z's brother. So A is Z's brother is true.
