When a vehicle passes, TV reception gets distorted. This is because A. Metal reflects radiowaves B. Spark plug creates electromagnetic disturbances C. Vehicle pollution affects the performance of the TV components D. Modern vehicles use electroignition system

The correct answer is: A. Metal reflects radiowaves.

When a vehicle passes, the metal in the vehicle reflects radio waves, which can cause distortion on your TV. This is especially common with older vehicles that have a lot of metal bodywork.

Spark plugs do create electromagnetic disturbances, but these are usually not strong enough to cause interference with TV reception. Vehicle pollution can also affect the performance of TV components, but this is usually not a major issue. Modern vehicles use electroignition systems, which are less likely to cause interference than older spark plug systems.

Here is a more detailed explanation of each option:

• Option A: Metal reflects radiowaves. This is the most likely explanation for

• Option B: Spark plug creates electromagnetic disturbances. Spark plugs do create electromagnetic disturbances, but these are usually not strong enough to cause interference with TV reception. The electromagnetic disturbances created by spark plugs are usually only strong enough to interfere with sensitive electronic equipment, such as computers and medical devices.
• Option C: Vehicle pollution affects the performance of the TV components. Vehicle pollution can also affect the performance of TV components, but this is usually not a major issue. The pollutants in vehicle exhaust can cause corrosion and other damage to TV components, but this is usually not enough to cause significant interference with TV reception.
• Option D: Modern vehicles use electroignition system. Modern vehicles use electroignition systems, which are less likely to cause interference than older spark plug systems. Electroignition systems use electronic components to ignite the fuel-air mixture in the engine, which produces less electromagnetic interference than traditional spark plugs.
