Answer: C. An agreement with local Native Americans.
Step-by-step explanation:
The Pilgrim-Wampanoag peace treaty (1621) was a defensive alliance signed at the Plymouth settlement between the Plymouth colonists, serving King James I, and Massasoit, chief of the Wampanoags. Both groups agreed to not harm each other, on what would become the first treaty between American colonists and a Native American tribe. It lasted for over 50 years.
