773. The last “wild” Indian in North America, according to anthropologist Alfred Kroeber, was the lone survivor of California’s lost Yahi tribe, which staggered out of the mountains near Lassen Peak in 1912, deep in mourning for the last of his companions, expecting to be butchered and eaten by white ranchers.

(A) which

(B) who

(C) that

(D) the survivor having（B）

(E) having

答案是b，但是我觉得who从句明显在这里作为插入语是不能跳着修饰前面的survivor的，而如果就近修饰Yahi tribe，也不合理，所以我觉得好咸广大案都不怎么好

那你选什么,which代物,who代人,which可以修饰tribe,who不可以,你觉得哪个有更大的歧义呢?
