请教SC问题

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

问题1： they代表的是depressed property values, whose我认为是应该是指的是资产的，因为equity已经代表价值了。那么whose引导的是什么从句？先行词是什么？
问题2：像for homeowners这样的介词结构中的homeowners可以作为先行词吗？
问题3：they离whose很远，这样可以引导从句吗？不是说先行词要跟引导词紧接着吗？
问题4：C选项错在哪里了？答案中说，their不能至homeowners，可是我认为their指的是资产的，不知道这个问题出在哪了？

谢谢大家！

谢谢，我是equity的意思理解错误了。所以导致题目没看懂。

1.Whose引导非限制性定语从句，antecedent是homeowners，
2 yes
3. 没懂，先行词是homeowners啊
4.devastating的是dpv而不是homeowners，指代错误
