Final answer:
The Georgia Charter did not allow Catholics to settle in Georgia. It granted religious freedom for all Protestants and eventually permitted a group of Jews to stay in Savannah. Option a is the correct answer.
Step-by-step explanation:
The religious group that was not allowed to settle in Georgia, according to the Georgia Charter, was Catholics. The Charter granted religious freedom for all Protestants and, despite not being initially included, a group of Jews was allowed to stay in Savannah. The Charter emphasized religious liberty with the exception of Catholics, reflecting the religious composition of the colony that largely included Protestant religious refugees from various parts of Europe.
