A is the correct answer.
The purpose of separation of power is to keep power from being concentrated in one branch of powers.
So, instead, the Constitution divides powers up and makes the branches dependent on each other and responsible to each other with a system of checks and balances.
Roman consuls were the two people who were the chairmen of the senate and served the board of advisers. Each of them had two legions under their command. So in a sense it could be B and D.
