Which principle provides for a system in which government deserves its power from the governed

The principle which provides for a system in which the government derives its power from the governed is the popular sovereignty.

Explanation:

Popular sovereignty is the sovereignty where the government or say, the state authority makes a government. This formed government will be given sustenance only by the consent of the people. Therefore, the word popular is used as it will be the consent of the people to whom the popularity will fall in order to sustain a formed government.

The consent is expressed through the elected representative of the people. The elected representative thereby, serves as the source of their political power and so the principle providing system for the government deriving its power from governed is called Popular sovereignty.
