The correct answer is A. An assembly of all citizens would have to take control from an elected group.
Step-by-step explanation
Representative democracy is a form of government in which the people choose their rulers by vote, who have the function of representing the different groups that makeup society and governing according to their interests. On the other hand, direct democracy is that form of government in which the people rule directly without the need for representatives, but rather all citizens must actively participate in government. Therefore, the correct answer is A. An assembly of all citizens would have to take control from an elected group.
