Answer:
B. Develop a relationship with Native Americans
C. Make lots of money
Step-by-step explanation:

One important benefit was developing relationships with Native Americans. Although this relationships were not always positive: Native Americans were often subject to brutal treatment.
And the second benefit was economic: the New World provided large amounts of wealth to European explorers and colonists, and also to European monarchs.
