Answer:
Correct answer is A: Check and balances.
Step-by-step explanation:
The principle of Check and Balances, which is pretty much one of the most defining and important characteristics of the United States as a nation, and as a state, establishes that there will be separation of powers between the three branches of government so that no one can overcome the other, take over the other, or overpower the other. As such, all three branches are separate, and have their own tasks to perform, but they also interconnect in such a way that the three have equal power and check each other through the system of check and balances. In this case, the Executive Branch, at the head of the President, is given by Constitution the power to name people in vacancies while the Senate is in Recess, through Commssions, in order for the Excutive branch to be able to continue functioning without being completely dependent on Congress for it.
