Which statement is true regarding advice code 2C?

The statement about advice code 2C being that it indicates no substitutions can be made is correct because advice codes are used to provide specific instructions about how to handle a requisition. Code 2C communicates that the requesting activity has a strict requirement for the exact items ordered. This means that if there are no available stock or alternate items, the supply system will not make substitutions, as doing so could impact mission readiness or specific operational requirements.

Options that suggest full and partial shipments, backorders being encouraged, or the limiting of this code to low-priority items do not accurately reflect the purpose and function of advice code 2C, which is focused on maintaining the integrity of the specific item requested. The insistence on no substitutions ensures that the integrity of the requested item is preserved, aligning with operational needs.
