East and relocate further west.

It is false that three of the five tribes favored the legislation because they  welcomed the opportunity for westward expansion.

Explanation:

The Indian Removal Act was a law passed by Congress in 1830 with the aim of legalizing the relocation of the American Indian tribes that were located east of the Mississippi, taking them to what today is Oklahoma. This rule was clearly rejected by the native tribes, who considered their territories as their ancestral property, and did not see possible a separation of their peoples from their territories, given their cultural and religious conception. Therefore, it is false that there were tribes that supported this norm.
