Final answer:
A service member may be granted a maximum of 90 days reenlistment leave upon immediate reenlistment, which does not correspond to any of the multiple-choice options provided. The note on the president's deployment of troops refers to the War Powers Resolution parameters.
Step-by-step explanation:
A service member may be granted reenlistment leave for a maximum of 90 days, which must begin immediately upon reenlistment. None of the options A. 5 days, B. 10 days, C. 15 days, or D. 20 days are correct based on current U.S. military policy. This leave is designed to offer those who have committed to further service an opportunity to rest and spend time with family before continuing their duties.
Additionally, the information provided regarding the deployment of troops is a reference to the War Powers Resolution, which requires the President to notify Congress within 48 hours of committing armed forces to military action and forbids armed forces from remaining for more than 60 days, with a further 30-day withdrawal period, without a congressional authorization for use of military force or a declaration of war.
