The correct answer is C. Promoting cultural assimilation.
Step-by-step explanation:
The Carlisle school, which was founded in Pennsylvania at the end of the 19th century, focused on making young Native Indians integrate into the dominating white culture. Due to this, children at Carlise school were forced to dress like white people, were given European or non-native names, and were required to leave Native American ideas and behaviors.
