The correct answer is C) 8 hours. VHF Survival Craft Transceivers, which are emergency radio devices used on lifeboats and life rafts, are required to have a minimum battery capacity of 8 hours of continuous operation, as per the regulations set by the U.S. Coast Guard. This ensures that the transceiver can maintain communication for a sufficient duration in the event of an emergency, allowing rescue efforts to locate and assist the individuals in distress. The other options are incorrect because 4 hours (A) and 6 hours (B) do not meet the minimum regulatory requirement, while 12 hours (D) exceeds the standard.
