The correct answer is 2) The power of government comes from the people.
When making the US Constitution, the Founding Fathers wanted to ensure that the government being created would be responsive to the needs of American citizens. This is why they created a government in which citizens have the power to determine their representatives.
This is evident in the preamble, as it starts with "We the people" insinuating that this constitution is a result of the power given to Americans that allow them to make this structure of government.
