Turning off the navigation lights during a wing fire in flight is a prudent action because these lights can generate heat and potentially exacerbate the fire situation. Navigation lights, intended for visibility to other aircraft, may not provide any strategic benefit during an emergency like a fire. By turning them off, you reduce any additional risk factors while managing the emergency.

In contrast, the other lights such as the landing lights, wing lights, and strobe lights have different roles. The landing light is typically used to illuminate the runway during approach and landing, while wing lights are often used to enhance visibility of the aircraft's wings during critical phases of flight. Strobe lights are used to increase the aircraft's visibility during the day and night. Their operation or deactivation would be more context-dependent rather than a direct action to mitigate a fire hazard. Therefore, focusing on minimizing all possible sources of heat and ensuring clarity in emergency protocols, turning off the navigation lights is the most appropriate choice.
