Answer :
In the context of favoring farmers in the Colorado River's Lower Basin, a policy stance that would likely support farmers is option B: Water use should favor those who have settled the basin first.
1. This policy stance would give priority to farmers who have historically settled in the Colorado River's Lower Basin. It acknowledges their long-standing presence and use of the water resources in the area.
2. By favoring those who have settled the basin first, the policy would aim to provide stability and security for farmers who have relied on the water for their agricultural activities over time.
3. This approach could also be seen as a way to recognize and protect the rights of farmers who have established themselves in the region and have built their livelihoods around water usage in the Colorado River's Lower Basin.
Overall, option B aligns with a policy stance that considers historical settlement patterns and prioritizes existing water users, such as farmers, in the Lower Basin.
