补充-097里面they和their的指代问题

v521

Unlike that of human beings, who waste away when they go without food for long periods, hibernating bears exist for months on only their excess fat.
(A) Unlike that of human beings, who waste away when they go
(B) Unlike human beings, who waste away when they go
(C) Unlike human beings, wasting away when going
(D) Dissimilar to human beings, wasting away when（B）
(E) Lacking similarity to human beings, who waste away when

答案是b，但是划线的they跟未划线的their的指代不同啊，不会产生歧异么？我记得这种情况不以啊，咋个问题？

谢谢
