The correct answer is B) Maritime Administration. The reasoning is that the Naval Control of Shipping publications, including ATP-2 Volume II, are maintained and distributed by the Maritime Administration (MARAD), which is the agency responsible for overseeing merchant marine operations. If a copy of a required publication is missing, the appropriate action is to request a replacement from MARAD, as they are the custodian of these materials. The other options are incorrect because the Chief of Naval Operations and the local Operational Control Authority would not be responsible for maintaining or replacing these specific maritime publications, and the Coast Guard, while involved in merchant marine oversight, does not directly manage the Naval Control of Shipping publications.
