Deck General: Every fishing vessel required to have a general alarm system must test it ______...

USCGQ Staff, please look at this one. 46 CFR Section 28.240 (e) states "A general alarm system must be tested prior to operation of the vessel and at least once each week thereafter", which represents answers ""A and "B".
