Answer:
b. His tolerance of racial and religious differences.
Step-by-step explanation:
Roger Williams was a theologian, author and Puritan minister who staunchly support the issues relating to freedom of religion. He also advocated for the separation of the state and church, fair dealing of cases regarding American Indians and was himself one of the very first abolitionists.
Roger Williams established the Providence Plantations, later known as the Colony of Rhode Island. He also founded the first Baptist Church in America in 1638. He had migrated to America for he felt that the Church of England from which all power lies, is not a just way of governing any nation. So, he started advocating for the wrongs in the world, especially about the separation of the powers and duties of the church and the state and the statuses of American Indians and the Blacks/ slaves in America.
