Answer:
C - A body called the assembly determined the laws of commerce.
Step-by-step explanation:
This form of government, also called direct democracy (because citizens participated in both the creation of laws and their approval) differed from other forms of government in the ancient world because the assembly, this group of citizens that rotated every year, could determine the laws of commerce and any other type of law depending what was being discussed. This assembly of 500 citizens promoted laws which were then approved or not by the rest of citizens.
