Concept:A logical conclusion must be directly supported by the given statement without adding new information or making general assumptions.Explanation:The statement explicitly says that urban areas expanded rapidly but public transport lagged, leading to increased traffic congestion and air pollution. Conclusion I states that lack of adequate public transport contributes to pollution; this is directly supported by the statement. Conclusion II says improving public transport can reduce urban mobility problems; the experts’ recommendation for investments in metro, electric buses, and last-mile connectivity implies that better public transport would address the issues. Conclusion III claims urban growth is always negative; the statement only highlights a problem caused by insufficient infrastructure, not that growth itself is inherently bad. Therefore, conclusions I and II necessarily follow, but III does not.Answer:Only conclusions I and II follow. Option B.
