The one choice that best describes is religious freedom because it was the main reason they escaped England. Even though there were a variety of reasons, it has to be taken into account that the purpose to rebuild a society in which the concept of God and hard work came hand-in-hand was salient. Faith and the sense of freely practising their beliefs was what carried them through the difficult task of settling in an unknown part of the world, with little chances of survival at first.
All that came after the first settlers later on became part of the reason for looking for the freedom the colonies could provide.
