Question 95Navigation General

The correct answer is A) O (IMMEDIATE). When proceeding under Naval Control of Shipping (NCS) and it becomes necessary to send a distress message, the appropriate precedence to assign is IMMEDIATE (O). This is because a distress message indicates an urgent situation where life or property is in immediate danger, requiring the fastest possible response. The IMMEDIATE precedence is used for messages that demand immediate delivery and have precedence over all other messages except FLASH. The other options are incorrect because: B) FLASH (Z) is reserved for the most critical situations that directly affect national security or defense; C) ROUTINE (R) is for non-urgent messages; and D) PRIORITY (P) is for messages that are important but not as time-sensitive as IMMEDIATE.
