How many days may Commanders defer confinement on bread and water or correctional custody?

The correct answer is based on military regulations that allow Commanders to defer confinement on bread and water or correctional custody for a maximum of 15 days. This provision gives Commanders a limited amount of time to manage disciplinary actions while still maintaining good order and discipline. It reflects a balance between the need for accountability and the welfare of the service member, ensuring that the confinement is not prolonged beyond a reasonable period.

The other options are incorrect as they exceed the stipulated timeframe according to military guidelines, which specifically set this limit at 15 days to avoid excessive punishment and provide an opportunity for potential rehabilitation or reassessment of the situation.
