Answer:
The correct answer is A: a presidential order to carry out a policy or policies described in a law passed by Congress.
Step-by-step explanation:
Executive orders are issued by the President holding office and do not require approval from Congress. Executive orders have the force of law. Based on their statutory or constitutional powers, US Presidents issue these directives to federal agencies, heads of departments, or other employees. After executive orders are published in the Federal Register, they take effect. Only the US President is entitled to overturn an executive order. Presidents usually issue this type of orders because it is part of their management of the executive branch, it is a way of administering the federal agencies, and through these directives, Presidents carry out their presidential responsibilities.
