[求助]非常非常急切的再请教各位NN大全757

5. The Forbidden City in Beijing, from which the emperors ruled by heavenly mandate, was a site which a commoner or foreigner could not enter without any permission, on pain of death.

(A) which a commoner or foreigner could not enter without any permission,

(B) which a commoner or foreigner could enter without any permission only

(C) which no commoner or foreigner could enter without permission,

(D) which, without permission, neither commoner or foreigner could only enter,（C）

(E) which, to enter without permission, neither commoner or foreigner could do

想问各位,在GMAT里，which不是只能用于非限定从句吗（一般中间有逗号）？为什么这里直接跟在要修饰的名词后面呢？

还有B，是不是意思变成：平民和外国人都可以没有许可地进入，违则处死，意思和原句要表达的意思相反？

严重感谢大家！！！

楼上GG, 对呀,这我明白-但就是不明白WHICH前面为什么没逗号，GMAT里面which非限定修饰时一般情况都是有逗号的...

谢谢楼上mm！是不是去掉which成分，后面的on pain of death就变成修饰site,就错了？
