(B)  they can potentially devastate homeowners in that their

(C)  for homeowners they are potentially devastat­ing, because their

(D)  for homeowners, it is potentially devastating in that their

(E)   it can potentially devastate homeowners, whose

答案是A，但While depressed property values can hurt some large investors,里有2个复数名词，划线部分的they不会引起歧义吗？

请指教，谢谢！

楼上说的对。我的理解，一般从句中有两个以上复数名词在主句的代词之前，必须保持从句主语和从句主语的一致。如果不能保证这个一致关系，那么认为这个代词指代不清。如

As researchers continue to probe the highly expressive vocal and postural language of wolves, their close resemblance to dogs has become ever more striking.

这个指待就是有问题的。因为应该指待从句主语－researchers，但是明细句意是指待wolves，所以犯了指待不清的问题。
