Answer:
Option B. Consulting them regarding cleanup and restoration efforts.
Step-by-step explanation:
After the Hanford Nuclear Site was closed, the U.S. government consulted with nearby Indigenous peoples regarding cleanup and restoration efforts. This decision reflects a growing recognition of the importance of Indigenous peoples' sovereignty and their right to participate in decisions that affect their communities and lands. The government recognized that the Hanford Nuclear Site had significant impacts on the health and well-being of Indigenous peoples in the region, and involving them in the cleanup and restoration process was seen as a way to address their concerns and promote environmental justice.
