The assimilation of Native Americans was a goal of the Dawes General Allotment Act

Thus the correct answer is Option D

Explanation:

Dawes act is called General allotment which surveyed the American tribal lands and allotted specific piece of land to every American Household. It allowed Native Americans practice agriculture farming and to be self-reliant but there were many disadvantages of this land allotment act.  

The land which was given was not fertile and mostly Native Americans sold their lands in order to lead their livelihood. Women were not given any rights to own the land and this led to selling it at the end.  

It also paved way for the uprising of many communities in Native America and the culture got eroded.
