BOTH INTERNATIONAL & INLAND Which vessel shall exhibit a rigid replica of the International Code flag "A"?

Correct Answer: Option A — a vessel engaged in diving operations

Rule 27(d)(iii) requires a vessel engaged in diving operations to display a rigid replica of the International Code flag 'A'. This signal is necessary to warn other vessels to keep clear and proceed at slow speed, as divers are in the water and the vessel is restricted in maneuverability.
