Correct Answer: Option B — 8291.0 kHz
HF distress communications follow a specific pairing of DSC frequencies and voice frequencies. For an alert sent on 8414.5 kHz, the corresponding voice frequency is 8291.0 kHz. This standardized pairing allows operators to quickly switch to the correct frequency for voice coordination after the initial digital alert.
