Where several rescue units are engaged in a search and rescue operation, one of will be designated as the On-Scene Commander (OSC). Which of the following descibes how this appointment will be made?

The role of OSC can only be taken by a naval ship with suitable command and control capability. In many regions, such vessels are permanently assigned on stand-by to assume such a role.

Marine diesel engines are normally provided with automatic protection devices which operate in the event of abnormal conditions arising.

Since the engine used for propulsion would usually be bigger the sudden stop would generate greater thermal stress which may damage the engine.

The vessel could continue to operate and manoeuvre without any electrical power at all as long as the main engine is still running.
