C. Made the Native Americans citizens of the US is the correct answer.
Explanation:
The Dawes Act of 1887 was passed to divide the tribal lands so that the land could be given to the Native american heads and individuals so that the traditional system of landholdings can be transformed into system of private property under government control so that the tribal could have capitalist relationship with property. The act was named after senator Henry L. Dawes of Massachusetts. It was amended in 1891 and 1906. The Dawes commission has already been set up in 1893 to to exclude the Indians under the act so that they could agree for the allotment plan. The commission was first to register the members of five civilised tribes and other Indians. The jurisdiction of tribal land was abolished by the Curtis Act. <em>The Dawes act managed to end the reservation system of the Indians and granted the citizenship to all the native Americans who accepted land grants.</em>
