Choice A is incorrect as the extract clearly states the importance of rainforests in absorbing carbon dioxide. Choice C, while true, is not directly related to the implied role of rainforests in regulating the climate. Choice D is also incorrect as the destruction of rainforests does have global consequences, such as contributing to global warming.
