Thank you very much Ms. Sue

You're very welcome, Marylyn.

Yes, your answer is correct. The principle of checks and balances refers to the system in which the three branches of government in the United States (legislative, executive, and judicial) have separate powers and responsibilities that serve as checks on one another to prevent the abuse of power.

In this scenario, option A states that Presidents can veto an act of Congress, which is an example of the principle of checks and balances. This power allows the executive branch to check the legislative branch by refusing to sign a bill into law and sending it back to Congress for reconsideration. By exercising this veto power, the President can prevent a bill from becoming law, providing a balance to the legislative branch's lawmaking authority.
