The text states that the distance traveled by private vehicles in the regulated area of London declined while more distance was traveled by high-occupancy vehicles and low-emission vehicles. This suggests that the congestion charge was effective in reducing traffic congestion by incentivizing the use of more sustainable modes of transportation. Additionally, the fact that low-emission vehicles were used more supports the claim that the congestion charge was effective in reducing emissions. Option A is partly correct, but it only focuses on emissions and does not account for the broader impact on transportation patterns. Option B is incorrect because it does not mention any changes in vehicle occupancy or type, which are key indicators of the effectiveness of the congestion charge. Option D is irrelevant to assessing the efficacy of the congestion charge.
