Vessels 12 meters or more must carry which signaling device along with a whistle?

• A. Horn
• B. Bell
• C. Flares
• D. Life Ring

Answer: (A)

The key idea is that larger vessels must have an audible signaling option beyond just a whistle. For vessels 12 meters or more, a horn is the standard additional signaling device used to produce a stronger, longer-range sound that can be heard over engine noise and in poor visibility. Flares and life rings are visual/safety gear, not the required audible signal in this context, and while bells are used in some regulations, the practice reflected here specifies a horn as the necessary companion to the whistle. So a horn best fits the requirement because it provides a clear, effective audible signal for other mariners when visibility is limited or when you need to attract attention.
