Montana Security Guard Licensure Practice Exam

Receiving a signal poorly usually means that the received signal is weak. In radio communication, the code "10-1" is used to indicate a weak signal. Options A, C, and D are not related to the concept of receiving a signal poorly, as they represent different codes used in radio communication for other purposes (e.g. "10-2" for a radio check and "10-3" for a stop signal). Therefore, option B is the most appropriate answer as it directly refers to receiving a signal poorly.
