Which Part addresses undertakings by contracting governments in radio communications?

• A. SOLAS Chapter IV Part A
• B. SOLAS Chapter IV Part B
• C. SOLAS Chapter IV Part C
• D. SOLAS Chapter V Part A

Answer: (B)

The part that addresses undertakings by Contracting Governments in radio communications is the section within SOLAS Chapter IV that handles radiocommunications. This portion sets out the obligations of governments to provide and regulate radio services, issue and manage licenses, and implement the safety radio systems (such as the GMDSS) as applicable. That focus on the responsibilities of governments, rather than on general provisions or on other radio-related topics, is what makes this part the correct choice. The other parts cover general provisions or different aspects of radio requirements and do not specifically outline government undertakings in radio communications.
