Answer:
C
Step-by-step explanation:
The first option is just outright not correct and makes NO sense
The bill of rights WOULD NOT prevent a civil war what so ever
D makes NO SENSE since the founding fathers modeled the Goverment to not have a king to begin with, the fought a war partially due to a King.
Leaving us with C, the bill of rights would set a line on where the Goverment could not touch the basic freedoms the Americans fought for in the Revoultionary War.
