Answer:
The correct answer is D) Outlaw Native American expressions of spirituality and cultural practices
Step-by-step explanation:
The Civilization Regulations act of 1880 is historically seen as a racially motivated government policy to curb the independence and freedoms of the native American tribes.
The American government wanted to increase the participation of Natives and believed that forced assimilation might be useful. Some would argue it was 'forced Christianize' as the act made it illegal to practice native American religions and other practices.
