Final answer:
The Indians told Cabeza de Vaca's group stories of great wealth in the far north to deceive them and make them leave. Therefore, the correct option is b. To deceive them and make them leave.
Step-by-step explanation:
The Indians told Cabeza de Vaca's group stories of great wealth in the far north to b) deceive them and make them leave. The Indians wanted to protect their own resources and territories, and by exaggerating the wealth in the far north, they hoped to mislead Cabeza de Vaca's group and make them venture further away. This tactic was used by Native Americans in various encounters with European explorers, as they sought to maintain their own control.
