Which fundamental principle of U. S. democracy does this excerpt describe?

B. checks and balances

C. right to a fair trial

D. legislative powers

This excerpt most represents the fundamental principle of Option B: checks and balances.

Explanation:

The balance of powers between the different branches of government are described in this passage from the US Constitution. While the passage most focuses on the power of the executive branch, meaning the president and his appointees, it also describes how the Senate has to consent to treaties by two thirds and that the Senate also provides advice and consent on other executive appointments. The excerpt describes how Congress has the power to decide who should appoint lower officers in the government representing another check and balance to executive power.

so,   determine the median of the data. 2, 3, 3, 4, 5, 7, 9

it is already arranged, count 3 times forward and 3 backward and the one left is your answer.

2,3,3,4,5,7,9
