🔍 Key Concepts

• SOLAS (Safety of Life at Sea) Convention certificates for different ship types • Difference between cargo ship vs passenger ship radio safety documents • Which documents listed are real SOLAS/ITU certificates and which sound unlikely

💭 Think About

• Which of these choices specifically mentions cargo ships and radio equipment, matching the situation in the question? • Does SOLAS normally use the term "safety permit" or "certificate" for ship compliance documents? • Are any of these choices clearly related only to Great Lakes or to a specific region rather than international voyages?

✅ Before You Answer

• Verify which option is an actual SOLAS cargo ship radio safety certificate name • Check that the chosen document would be issued after a successful inspection of the radio station on a large non‑passenger ship • Make sure the option you choose is international in scope, not limited to a specific waterway or local agreement
