I think that A might be the answer, since the text says that hybrid cars reduce emissions by up to 90%.
Answer: A. Hybrid cars are an effective strategy to fight pollution.
Explanation: The initial statement makes it clear that private vehicle use is the greatest contributor to air pollution, from which we can infer that solutions implemented in that area (private vehicles) will have a high impact on pollution levels. Therefore, reducing emissions by up to 90 percent makes hybrid cars seem like an outstanding option.
