主谓一致（特定的人群应该怎么判断谓语的形式），谢谢大家！

Greatly influenced by the Protestant missionary Samuel Kirkland, the Oneida was the only one of the five-nation Iroquois League who sided with the colonists during the American Revolution.

(A) was the only one of the five-nation Iroquois League who sided

(B) was alone of the five-nation Iroquois League when they sided

(C) alone among the five nations of the Iroquois League sided

(D) were the only ones out of the five nations of the Iroquois League in siding

(E) only of the five-nation Iroquois League had sided
答案C
问一道与选项不太相关的问题
the Oneida代表的不是一类群体吗？看了prep和Manhattan的解释，说像the American或者the French后的谓语都是复数形式，怎么和我的理解有点儿相悖呢，像这种特定的人群应该怎么判断谓语的形式呢？
谢谢大家~

这道题的考点是到底谁 sided with the colonists during the American Revolution  ，应该是Oneida自己sided with,而不是five-nation Iroquois League   sides with

恩，谢谢你的解答
这个我懂得，只是借用这道题问一下关于主谓一致的问题，特定人群的总称后都用复数的谓语动词吗？
