Which of the following best sums up the central idea of the paragraph formed after rearrangement?

The paragraph discusses how Asian countries are under pressure to adopt a carbon tax policy to tackle climate change.

The title is generic and it does not highlight that the policy is bound to face challenges in Asia. B is incorrect. The passage does not discuss the merits and demerits of a carbon tax policy. D is incorrect. The passage does not focus on the attitude of Asian policy makers. E is incorrect. The passage does not talk about the role of Asia in the fight against climate change.
