Which scenario is an accurate example of how branches of the federal government can check each other’s power ?

The president vetoes a law passed by Congress, but Congress overrides the veto with a two-thirds majority vote

Explanation:

The other examples are actually examples of a branch overreaching. They're examples of abuse of power.

The answer is a good example of checks and balances because the president, who was elected by the people, can veto a law that congress might have approved, but if Congress, also elected by the people, gathers in a significant majority, they can take down the veto. So the passing of a law absolute, but neither is the veto.
