Which of the following is a reason for administrative reduction of a soldier?

Administrative reduction of a soldier is primarily associated with misconduct because this involves behavior that violates military standards or regulations. Misconduct can include a variety of actions such as non-compliance with directives, legal issues, or other behaviors deemed unacceptable according to Army regulations. Such actions can undermine the trust and cohesion within a unit, and therefore, an administrative reduction serves as a way to maintain discipline and standards within the Army.

In contrast, performance reviews typically assess a soldier's capabilities and readiness for promotion rather than provide grounds for reduction. Overseas deployment has no direct impact on a soldier’s administrative status; it is generally a temporary duty assignment. Similarly, promotion eligibility pertains to a soldier's qualifications and readiness for advancement, which does not directly lead to a reduction in rank.
