In California, a lack of genetic variation in the Argentine ant has allowed the species to spread widely; (due to their being so genetically similar to one another, the ants consider all their fellows to be a close relative and thus do not engage in the kind of fierce intercolony struggles that limits) the spread of this species in its native Argentina.


A.due to their being so genetically similar to one another, the ants consider all their fellows to be a close relative and thus do not engage in the kind of fierce intercolony struggles that limits
B.due to its being so genetically similar the ant considers all its fellows to be a close relative and thus does not engage in the kind of fierce intercolony struggles that limit
C.because it is so genetically similar, the ant considers all its fellows to be close relatives and thus does not engage in the kind of fierce intercolony struggles that limits
D.because they are so genetically similar to one another, the ants consider all their fellows to be close relatives and thus do not engage in the kind of fierce intercolony struggles that limit
E.because of being so genetically similar to one another, the ants consider all their fellows to be a close relative and thus do not engage in the kind of fierce intercolony struggles that limits

我看到有的版本上这道题的C选项 是the ants considers 那就可定C不对了 可我这个版本不是呢？？而且给的答案也是C  
我觉得是后面limit的问题啊 前面说a lack of genetic variation 分明是一个limit 怎么会是C的limits呢
NN帮我看看吧~~

有两句话，用分号隔开
#1：In California, a lack of genetic variation in the Argentine ant has allowed the species to spread widely;

#2：because it is so genetically similar, the ant considers all its fellows to be close relatives and thus does not engage in the kind of fierce intercolony struggles that limits

limits是that定语从句的谓语，该从句的主语为the kind of fierce intercolony struggles，是单数
