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

Answer:
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.
