Q15:

The city has proposed a number of water treatment and conservation projects the cost of which raises water bills high enough so that even environmentalists are beginning to raise alarms.

1. the cost of which raises water bills high enough so that
   
   
   
2. at a cost raising water bills so high that
   
3. at a cost which raises water bills high enough so
   
4. whose cost will raise water bills so high that
   
   
   
5. whose cost will raise water bills high enough so that
   

我选的是A, 答案是D，现在想是想通了。

是不是A里面的enough有主观的含义？

the cost of which   和   whose cost 有什么区别么？？？？
