Answer:
B. Quakers
Step-by-step explanation:
Penn was the founder of the province of Pennsylvania, a colony of the United Kingdom that later would become the homonymous American state. The democratic principles he implemented in the colony served as a source of inspiration for the American Constitution.
William Penn was a Quaker and he founded the American Commonwealth of Pennsylvania in order to create a refuge for Quakers (but not only them, also other religious minorities from Europe).
