What sea area is defined as being within range of a shore-based MF station that provides for continuous DSC alerting?

Correct Answer: Option A — Sea area A2

Sea Area A2 is defined by the coverage range of at least one shore-based MF coast station, typically within 100 nautical miles. This area ensures that vessels equipped with MF DSC can maintain continuous distress alerting and communication with shore-based rescue authorities, bridging the gap between coastal and oceanic coverage.
