There are five relatives A. B, C, D, and E. Four of them each told a true situation, as follows: ①B is my father's brother, ②E is my mother-in-law, ⑧c is my son-in-law's brother, ④A is me Brother's wife. Everyone mentioned above is one of these five people (for example, "my father" and "my father's brother" in ① are all one of five people A. B, C, D, E ),. From this we can infer:. ['B and D are brotherhood.', "A is B's wife.", "E is C's mother-in-law.", 'D is a child of B.']
