The phrase "CAUTION WAKE TURBULENCE (traffic information)" is the correct way to communicate a wake turbulence cautionary advisory because it adheres to established aviation communication standards. The term "CAUTION" is specifically used in aviation to alert pilots about a potential hazard, in this case, wake turbulence, while still providing traffic information which may be relevant for flight safety without implying an immediate threat that requires urgent action. This phrasing allows pilots to be aware of the situation, prepare accordingly, and adjust their operations if needed.

Using terms like "WARNING" or phrases such as "BE AWARE OF" or "ATTENTION: WAKE TURBULENCE DETECTED" can create confusion or imply a more urgent risk than what the term "CAUTION" conveys. In aviation, precision in language is critical for safety and effective communication, and using the term "CAUTION" aligns with the protocols already established in air traffic control communications. Thus, option A is the most appropriate and correctly formatted phrase for wake turbulence advisories.
