The correct answer is number 4) to have a religious refugee of their own.
More than 1000 colonists inhabited the Massachusetts Bay Colony primarily to have a religious refugee of their own.
John Winthrop was the first governor of the Massachusetts Bay Colony. They founded the first town in the region and named it Salem. These Puritans were very strict in their conduct and professed utmost respect for their religious beliefs. Government and church were one of the same. There was no differentiation between one or the other. Indeed, to have the right to vote in the Massachusetts Bay Colony, people had to be members of the church. So it is correct to say that more than 1000 colonists inhabited the Massachusetts Bay Colony primarily to have a religious refugee of their own.
