Answer:
The correct answers is an executive order
Step-by-step explanation:
Executive orders are mandates from the president whose goal is to implement an specific measure. A president can regulate matters like war or immigration through executive orders. However, executive orders are also submitted for judicial review and the courts can nulify them if they are considered ilegal or inconsistent with existing laws. Executive orders also have the disadvantage over normal legislation of being dependent on the will of the sitting president, because they can be revoked at any time.
