Final answer:
The Puritans separated from England primarily due to religious persecution and their desire to reform or separate from the Church of England's corrupt practices. They sought to establish colonies where they could practice their Calvinist-based Protestantism freely, leading to the foundation of Plymouth by Separatists and Massachusetts Bay by reformers.
Step-by-step explanation:
Reasons for Puritans' Relocation to the New World
The Puritans found the need to separate from England and relocate to the New World because they found the Church of England to be very corrupt (option a). The Puritans desired to practice their Calvinist-based Protestantism without persecution and sought reforms that would eliminate Catholic-influenced practices within the Church. The Church's demand for conformity and treatment of Puritan ministers as outlaws prompted many Puritans to settle in the New World. Those in Massachusetts Bay aimed to reform the Church of England from within, whereas the Pilgrims of Plymouth were Separatists who believed in complete separation from the national church. In pursuit of religious freedom and to maintain their national identity, the Pilgrims first migrated to the Dutch Republic and then to Plymouth, Massachusetts, where they signed the Mayflower Compact, establishing a community based on their religious ideals.
