The correct answer is based on the role that anti-ice fluids play in preventing ice formation on aircraft surfaces. These fluids are designed to lower the freezing point of water and provide a protective layer that inhibits ice from adhering to critical surfaces such as wings, tail, and control surfaces. By applying anti-ice fluids before flight, dispatchers ensure that the aircraft maintains its aerodynamic properties and performance during winter weather conditions or when flying through icy clouds.

Other options, while important in various contexts, do not directly address the primary method of preventing ice formation on aircraft surfaces. Ground de-icing facilities are crucial for the preparation of the aircraft before takeoff, but they do not prevent ice in-flight. Engine heating systems are primarily focused on maintaining optimal operating conditions within the engines rather than on the exterior surfaces. Tire heating systems, while relevant for improving traction on icy runways, do not impact the prevention of ice on the aircraft's wings and fuselage.
