The Pennsylvania Dutch (“Deutsch”) were

A. Dutch settlers in Pennsylvania B. Pennsylvania settlers in Holland
C. Catholics who moved from Holland to Pennsylvania
D.wiped out by religious persecution
E.a mixture of German Lutherans, Mennonites, Moravians, etc.

I think it's C?

The Maryland Toleration Act assured religious freedom to? At first I thought it was Christians but then I started looking online & got answers like Catholics, protestants, & puritans? So I'm not sure which one is correct.

C is wrong

Catholics, Protestants, and Puritans ARE ALL Christian.

For the first question, the Pennsylvania Dutch ("Deutsch") were a mixture of German Lutherans, Mennonites, Moravians, etc. So the correct answer is E.

Regarding the second question about the Maryland Toleration Act, it provided religious freedom and protection to all Christians, including Catholics, Protestants, and Puritans. Hence, the correct answer is all of the above (Catholics, Protestants, and Puritans).
