Who is responsible for transmitting a message stating that distress communications have ceased?

Correct Answer: Option A — The Rescue Coordination Center (RCC) controlling the distress communications

The Rescue Coordination Center (RCC) is the primary authority responsible for managing the distress incident. Consequently, the RCC is the only entity authorized to formally announce the cessation of distress communications, ensuring that all participating stations are aware that the emergency traffic has officially concluded.
