Which of the following did the Organic Act establish?

A. tribal reservations

B. seven counties in Oklahoma Territory

C. laws that dealt with squatters

D. the Cherokee Commission

It seems like the answer is B, the organic act is an act of the United States Congress that establishes a territory of the United States or an agency to manage certain federal lands. But that doesn't seem to be an option here.

I think it established 7 counties in Oklahoma Territory
