Which of the following is the correct dialog for relieving a helm watch?

Correct Answer: Option B — "Cadet A relieving Cadet B steering course X, checking course Y." "Cadet B stands relieved."

Standard bridge protocol requires a clear, concise hand-over procedure. The relieving helmsman must state their intent, the current course, and verify the course with the outgoing helmsman. The outgoing helmsman confirms the relief, ensuring the conning officer is aware that the helm has been successfully transferred without any loss of control.
