• A. Green
• B. Red
• C. Blue
• D. Yellow

Answer: (C)

Taxiway edge lights are designated by the color blue. This color serves a specific purpose in airport operations, as it clearly delineates the edges of taxiways for pilots during both day and night conditions. Blue lights help guide aircraft along the taxiway routes, ensuring safe navigation and reducing the chances of confusion with runways or other areas of the airport.

In contrast, green lights typically designate runway centerlines, red lights indicate the edges of runways or areas where aircraft should not go, and yellow lights are often used to signify taxiway centerlines or specific instructions. Understanding these color codes is crucial for maintaining safety and efficiency in airport operations.
