Puritans were called the Roundheads. Option C is correct.
Roundheard is the term assigned to those who were supporters of the Parliament of England during the English Civil War.
The Parliamentary was supported by almost all the Puritans in England. The Puritan men used to wear their hair very short at a time when much longer hair was fashionable. As a result, their heads looked rounder than those of men with long hair. For this reason, they came to be called the Roundheads.
