Statement: "Electric cars reduce air pollution."Inference:

Explanation

The correct answer is Option A: 'Traditional cars contribute to pollution.' The statement 'Electric cars reduce air pollution' suggests that electric cars are a cleaner alternative to traditional vehicles, which can be inferred to contribute to pollution. Option B is incorrect because the statement does not support banning all cars, only that electric cars are less polluting. Option C is incorrect as the statement does not provide evidence of global air quality improvement, merely the potential of electric cars to reduce pollution. Option D is irrelevant to the statement, which focuses solely on pollution, not road safety.
