What word is spoken three times and transmitted before the call in safety signals?

The correct answer is "YYY," as it is a proword used in maritime communication. "YYY" is transmitted three times before a safety call to alert those receiving the message that a safety signal is being sent. This practice ensures that the intended recipients are aware that the communication pertains to safety issues, allowing them to pay closer attention and take appropriate action if necessary.

While the other options—"SECURATE," "NC," and "Orange"—are terms related to communication or safety in specific contexts, they do not serve the same function or convey the same urgency as "YYY." "SECURATE" is not a standard term used in emergency communication. "NC" typically stands for "No Communication," which does not fit the context of signaling safety. The color "Orange" might be associated with warning signals but is not the designated term used in safety transmissions. Thus, "YYY" stands out as the correct choice for its specific role in maritime safety communication.
