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 ants considers all its fellows to be a close relative 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

给的答案是D,

但我觉得该题A,C,D,E都有单复数指代问题,

Aue to their being so genetically similar to one another: 原文是ant, species,包括划线部分后面也是in its native Argentina 都是单数,故A错

C:划线部分后半句the ants considers all its fellows 矛盾 错

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划线部分三个复数名词和后面的in its native Argentina 矛盾, 错

E:the ants consider all their 和后面的in its native Argentina 矛盾, 错

故,虽然B中的DUE TO不是很好,但符合correct原则. 我选B

请指教:
