The correct answer is Assimilation
Step-by-step explanation:
The two photographs show a Native American has abandoned at least part of his culture because he does not wear the clothes and accessories that belong to Native American culture and he has cut his hair. Also, in general, he looks like a white settler. This shows assimilation because this man has learned values, norms, etc. of the main culture that was one of the European settlers during the 19th century. Also, it is expected not only his way of dressing has changed but also his beliefs, behavior, among others.
