Correct Answer: Option A — Will be transmitted on 2187.5 kHz or another DSC frequency, depending on the manufacturer.
The 'Distress Hot Key' functionality is manufacturer-dependent regarding which specific frequency is prioritized for the initial transmission. While 2187.5 kHz is a primary MF DSC frequency, the controller may be programmed to transmit on other mandatory DSC frequencies depending on the specific equipment's design and the operator's configuration.
