B, The publisher will publish 20 books to sell them online 句子结构是错的，逻辑主语是it，没问题；但to sell them作伴随状语修饰publish是不恰当的，因为用to意味着主句谓语动词引起了不定式的动作状态的改变，即出版这个动作导致sell状态的出现，但实际上出版时出版，卖是卖，我出版了也可以自己留着纪念或送人，不卖。所以不能做伴随状语
它也不能做定语修饰books，books不能sell books
所以sell要么是和publish并列，publish 20 books and sell them online, 要么作定语修饰books，publish books to be sold online。作定语时可否用不定式要看主语对该动作的控制力，books to be sold，主语是人，人可以决定sell还是不sell，所以用不定式。
