Concept:Identify the sentence that deviates from the central theme of transport infrastructure and its role in economic development.
Explanation:The theme sentence focuses on how transport infrastructure supports economic growth through better connectivity, reduced travel time, and improved trade efficiency.
Sentence A highlights highways improving logistics and regional market integration, which matches the theme.
Sentence B discusses renewable-energy subsidies and eco-friendly power adoption, which belongs to the energy sector rather than transport infrastructure.
Sentence C mentions upgraded ports enhancing export-import operations and industrial growth, which fits the theme.
Sentence D refers to modern railway systems promoting affordable mobility and reducing congestion, which also aligns with the theme.
Since sentences A, C, and D share the same transport-related theme, sentence B is clearly the odd one out.
Therefore, sentence B can be replaced with the highlighted theme sentence.
Answer:Option B
