Explanation: The "Securite" (pronounced "Say-cure-e-tay") signal, spoken three times, is the international radiotelephone safety signal under GMDSS regulations. Its purpose is to indicate that the station sending it has an important navigational or meteorological warning to transmit. This includes information vital to safe navigation, such as aids to navigation malfunctions, dangerous wrecks, or severe weather forecasts. Therefore, expecting a message concerning the safety of navigation (A) is correct. * **B) The safety of vessel or person is in jeopardy:** This describes the "Pan-Pan" urgency signal. * **C) A vessel is in need of immediate assistance:** This describes the "Mayday" distress signal. * **D) A Coast Station sending an important traffic list:** While Coast Stations send traffic lists, they do not use the "Securite" signal for this purpose; it is reserved for safety-related warnings.
