The above system of United States Constitution is showing three organs of the state i.e Legislative branch, Executive branch and the Judicial branch.
And below each division, their works are given. Aswecan were that, each of the organ is at same height which shows that they are practicing equal powers and they don't interrupt in each others work.
They practice the system of <u>Checks</u><u> </u><u>and</u><u> </u><u>Balances</u> to ensure that none of the organ is enjoying and grabbing too much.
So, the most appropriate option is:

Checks and balances system.
And, we are done !!

Hope this helped!
Good luck :p

It is the United States "Senate" that limits the president's ability to nominate federal judges, since one of the jobs of the Senate is to "confirm or deny" such appointments.
Because they have no common sense.
