C正确没有异议，但是我想问关于og解释“In B, the subject and verb agree, but the descriptive phrase placed between them creates an illogical statement because each cannot be wives; each can be one of the wives, or a wife”，而Each of Hemingway's wives这种说法是对的，B不对是因为“them Hemingway's wives”？

each of them 指的是她们中的每一个，单数

H's wives 指的是所有的wives, 复数

单复数相冲突了。
