Answer: (D)

Runway edge lights are white to clearly define the edges of the runway during periods of low visibility or at night. This consistent signaling is crucial for pilots when landing and taking off, ensuring they maintain proper alignment and positioning relative to the runway boundaries. The use of white lights enhances visibility and decreases the risk of runway incursion or misalignment, thereby contributing to aviation safety. Each color used in airport lighting has specific meanings and purposes, and white lights for runway edges is a standardized feature across most airports globally.
