Step-by-step explanation:
The term in Andrew Jackson's message to Congress "on Indian Removal" that has the most positive connotation is "benevolent policy." In the context of his message, Jackson described the removal of Native Americans as driven by a benevolent policy of the Government, suggesting that the policy was meant to be kind and helpful, although historically, this was a contentious and forced removal.
