Question 66Navigation General

The correct answer is B) 3 hours. In a national emergency, when communicating via the Navy, messages are sent by precedence. A message designated as PRIORITY will be delivered within 3 hours. This is the standard protocol for PRIORITY messages in the Navy's communication hierarchy, where higher precedence messages take priority over lower precedence messages for more timely delivery. The other options are incorrect because 30 minutes is the standard for IMMEDIATE messages, 10 minutes is too short for a PRIORITY message, and 6 hours is the standard for ROUTINE messages, which have the lowest precedence.
