20。 The hognose snake puts on an impressive bluff, hissing and rearing back, broadens the flesh behind its head the way a cobra does, feigning repeated strikes, but, having no dangerous fangs and no venom, eventually, if its pursuer is not cowed by the performance, will fall over and play dead.

(C) broadening the flesh behind its head the way a cobra does and feigning repeated strikes, but it has no dangerous fangs and no venom, and

(D) broadening the flesh behind its head the way a cobra does and feigns repeated strikes, but with no dangerous fangs and no venom, and

E的错误是那个逗号应该用and

我想请问关于C中的and前面的这个逗号，如果and前有逗号，后面不是应该跟一个完整的句子吗？

为什么后面直接是will fall……

困惑！
