The survival radio and its protective cover shall be packed with which of the following?

The survival radio and its protective cover are specifically designed to be packed with the ship's survival craft. This is essential for several reasons. First, placing the survival radio with the survival craft ensures that it is readily available when needed, thus enhancing the chances of successful communication in a rescue situation. The survival craft is equipped for emergencies and is designed to keep those aboard safe while awaiting rescue, making it the logical location for crucial safety equipment like the survival radio.

The other options may contribute to safety, but they do not serve the same purpose as keeping the survival radio and its protective cover with the survival craft. A life jacket is an individual safety device that is worn, not stored alongside the radio. Similarly, a fire extinguisher is meant for fire emergencies and would typically be located in a central access point on the ship rather than with specific survival gear. Emergency flares, while important for signaling in an emergency, are not as essential as the radio for consistent communication and coordination in rescue attempts. Thus, the optimal and practical choice is to keep the survival radio with the ship's survival craft for effective emergency readiness.
