Well, I took the test twice and it's neither B or D. So, it is either going to be A or C.
Answer:
Letter D. It oversees operations of various agencies in the executive branch.
Explanation:
Montesquieu, in suggesting in the eighteenth century a system composed of the executive, legislative, and judiciary, thought of a way to limit powers. In this way, the powers though independent of each other should act in balance. In order not to abuse the executive, it was up to the other powers to supervise it. Thus, the oversight of executive agencies by the legislature acts as a counterweight, that is, a way of maintaining balance over the executive.
