The correct answer is A) Speaking in their native languages.
American Indian boarding schools were developed in America during the late 19th and early 20th centuries. The goal of these schools was to assimilate Native Americans into "normal" American culture. This meant learning the English language, dressing like white Americans, and having short hair. This assimilation process meant that Native American students could not speak their own native language or practice any of their customs. This resulted in the destruction of Native American culture for several different tribes across the United States.
