XDF蓝皮书 一道语法题 （求助）

    There is no legal limits, as there are for cod and hadock, on the size of monkfish that can be caught, a circumstance that contributes to their depletion through overfishing.

    A.There is no legal limits, as there are for cod and hadock, on the size of monkfish that can be caught, a circumstance that contributes to their depletion through overfishing.

    C.There are legal limits on the size of cod and haddock that can be caught, but not for monkfish, which contributes to its depletion through overfishing.

这道题答案选A，其它BDE很容易排除，可是觉得剩下的两个选项也不对，首先monkfish应该是单数，在A中却用复数their指代

而c中又不对称

是不是这样的呢？请NN指点一下

^_^

C选项里面的which应该是指代legal limits的，但是却跟在了monkfish后面，造成了逻辑上的混乱，而且整句句子读下来觉得比较乱，当初就是怎么想得，所以排除了c

monkfish　这里应该是指鱼群，表示复数。字典里有：There are plenty more fish in the sea。还有就像有一题，“The Shang” 指商朝的人，用的谓语也是复数。

C意思与原文不一致。
