Final answer:
The westward expansion of the U.S. was not carried out while respecting the rights of Native Americans due to the conflicting interests of settlers.
Step-by-step explanation:
The westward expansion of the U.S. could not have been carried out while respecting the rights of Native Americans. Option b) No, due to the conflicting interests of settlers is the most accurate choice. As American settlers pushed westward, they came into conflict with Native tribes that had long been living on the land. This led to violence, forced removals, and the transformation of tribal cultures, ultimately resulting in the displacement and marginalization of Native American communities.
