The correct option is A. The main goal of federal indian policy from the late 1880s through World War II was americanizing native peoples.
That era, between the 80s and World War II is known as the Allotment and Assimilation era. During this time period, the main goal of the country was to grant some property to Native Americans and help them become more akin to Europeans and Americans who inhabited in the country.
