A fund manager buys six types of funds: A. B, C, D, E, and E; not B and D at the same time; if you don't buy D, you don't buy C; or you don't buy A or B; if If you buy Wu and Ji at the same time, then you also buy C. Based on this, you can infer: (1) if you buy C, then buy D; (2) if you buy A. then buy D; (3) if you buy B, then not at the same time Buy Wu and Ji; (4) If you buy Wu and Ji at the same time, then buy Ding. In the above reasoning, is it correct? ['.', '.', '.', '.']
