A method commonly used to prevent carburetor icing is to

preheat the intake air.
mix alcohol with the fuel.
electrically heat the throttle valve.
increase engine speed.

The correct answer is: preheat the intake air.

Preheating the intake air is an effective method used to prevent carburetor icing because it warms up the air before it reaches the carburetor, which helps to prevent any moisture in the air from freezing and blocking the carburetor. Option B (mixing alcohol with fuel) is not as effective because it can dilute the fuel and reduce engine power. Option C (electrically heating the throttle valve) is not as efficient because it only heats one part of the carburetor and may not prevent icing in all areas. Option D (increasing engine speed) can actually increase the risk of carburetor icing because it causes a decrease in air temperature due to the increased air flow. Therefore, preheating the intake air is the best option for preventing carburetor icing.
