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.

(A) broadens the flesh behind its head the way a cobra does, feigning repeated strikes, but, having no dangerous fangs and no venom,

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

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

(C) 正确, 使用伴随状语broadening…and feigning…作为伴随成分修饰主句,和hissing构成并列结构;用and连接两个句子,表达正确
        

句子结构: The hognose snake puts on… hissing…, broadening…, feigning…, but it has no…

and no, and,...,…, will fall over and play dead.

疑问: C的结构没有看懂，那么多伴随状语并列，不是应该在最后加and么？

这里hissing and rearing back,broadening ...and feigning....的关系如何？

我觉得broadening ...and feigning....是做put on 的伴随状语，但并不是和hissing and rearing back并列，因为这是一个名词结构，与bluff(adj.)并列做put on的宾语。GMAT里面这样的结构很多，如confusing ballots，defying effort... 很迷惑人

另外，这句话也不是用and连接，而是用but。but后面的结构是it has...,and will fall...。

其实整体看这个句子的话，从未句末未划线的will fall可以更容易的判断出C选项正确，因为只有C给will fall提供了主语it.

更正一下，hissing and rearing是和bluff并列修饰back，做put on的宾语，完整的理解这个短语：an impressive bluff, hissing and rearing back.“一个令人印象深刻的虚张声势、嘶嘶作响的挺直的后背”
