a. anglicans
b. catholics
c. king
d. puritans

The answer is d.  Puritans.  They were already at odds with Charles’ religious practices which he imposed on the Puritans.  To add to the tension, they were angry that the King did not convene Parliament and had acted without the consent of the Parliament.  This would lead to the English Civil War that resulted in Charles’s imprisonment and execution.
