Final answer:
Tecumseh's stance reflected in the quote advocates for the unity of Native Americans to oppose white settlement, as land was deemed a common resource not to be sold.
Step-by-step explanation:
Tecumseh's feelings about western settlement are clearly expressed in his conviction that the land belongs to all Native Americans collectively and should not be sold or divided, especially not to outsiders who would claim it all for themselves. The reflection of this attitude is best summarized by option b. Native Americans should unite to oppose white settlement. Tecumseh's outrage was rooted in the historical context of White settlers encroaching on Native American lands, often violating treaties and agreements, and the federal government's failure to uphold these treaties. He believed that the land was a common resource that should not be sold, and he considered it necessary for all Native Americans to come together in defense of their shared rights to the land.
