70% to pass

In a national emergency, when communicating via the Navy, messages are sent by precedence. A message designated FLASH will be delivered within _______________.

A 3 hours to start of business the following day
B less than 10 minutes
C 1 to 6 hours
D 30 minutes to 1 hour
AI Explanation

The correct answer is B) less than 10 minutes. In a national emergency, when communicating via the Navy, messages are sent by precedence. A FLASH precedence message is the highest priority and must be delivered in less than 10 minutes. This is a strict requirement set by military communication protocols to ensure the most critical information is relayed as quickly as possible during an emergency. The other options are incorrect because: A) 3 hours to start of business the following day is too long for a FLASH message, C) 1 to 6 hours is also too long, and D) 30 minutes to 1 hour is longer than the required less than 10 minutes for a FLASH precedence message.
