The correct option is C Growth v/s Greenery
Expl: The most appropriate title for the passage is Growth vs Greenery because this comparison is both explicit and implicit throughout the passage. Choice (A) would be appropriate if the author’s tone was critical. Choice (B) focuses only on green orthodoxy whereas the author explores all aspects of the subject – what developed and developing countries do or can do, how important is ecology to the well being of people etc. Choice (D) is irrelevant. Hence Choice (C) is the correct answer.
