Explanation: In the maritime mobile service, coast and government stations serve as control points for communications in their area of responsibility. To maintain order, efficiency, and avoid congestion, especially with multiple ships potentially wishing to transmit, these stations manage the flow of routine traffic. **C) Ship stations must comply with instructions given by the coast or government station.** This is correct because it reflects the principle of station control. The coast or government station, acting as the controlling authority, directs when a ship station may transmit routine traffic. This ensures the receiving station is ready, and prevents multiple ships from transmitting simultaneously, leading to unreadable signals. **A) & B) Shipboard radio officers/licensed on duty operator may transmit traffic when it will not interfere / decides the order and time.** While the ship's operator is responsible for *executing* the transmission, the ultimate *determination* of when to transmit routine traffic to a controlled coast or government station is typically dictated by the receiving station to manage traffic flow efficiently. Unilateral transmission without direction can lead to disorganization. **D) The precedence of conventional radiocommunications is determined by FCC and international regulation.** Regulations define the *priority* of different *types* of messages (e.g., distress, urgency, safety, routine). However, they do not dictate the specific *timing* of a routine transmission to a specific station; that operational control rests with the receiving coast or government station.
