Answer:
The Base Commander typically has the authority to waive the 24-month inventory requirement due to unforeseen circumstances, potentially providing an extension of up to 60 days.
Step-by-step explanation:
The individual who may waive the 24-month requirement for required inventories due to unforeseen or unavoidable conditions is typically determined by the policies and procedures of an organization or, in the case of the military, specific service regulations. For the US Air Force, for example, it's generally within the purview of the Base Commander to grant such waivers. The number of days that can be allotted as an extension also depends on these policies. While the answer to this question may vary based on the exact context and organization's procedures, one potential answer relating to an organizational setting could be option C) Base Commander; 60 days.
