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
I understand the "the Oneida"=Plural noun
Eliminate A and B
As for E, "had sided" makes it illogical, influenced......should happen first.
How about C and D?How can I eliminate them?
Thanks for the answer
