[求助]关于指代， OG11（紫）19题

19．  While depressed property values can hurt some large investors, they are potentially devastating for homeowners, whose equity-in many cases representing a life's savings--can plunge or even disappear．

(A)  they are potentially devastating for homeowners，whose

(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

题目中they的指代，看起来既可能指代property values, 又可能就近指代investors。放在这里不会出现指代问题么？虽然下面5个选项看起来都有指代问题，A似乎相对来说比其他几个选项清楚点，但是逻辑指代不是OG常考点么？怎么自己又要犯呢？

猜测：句子开头用了while，表示了对比关系，所以说对比的两个分句主语是一致的？

请指点。

是对比,没错,但你要看对比的对象.它是说depressed property不光对large investor有影响,也对homeowner有影响,一大一小两个对比

另外,while/although/even though的从句主语一般是主句中的主语.不然they一般是就近指代
