Climate change is likely to expose a large number of people to increasing environmental risks forcing them to migrate. The international community is yet to recognize this new category of migrants. There is no consensus on the definition and status of climate refugees owing to the distinct meaning the term refugees carry under international laws. There are still gaps in understanding how climate change will work as the root cause of migration. Even if there is recognition of climate refugees, who is going to provide protection? More emphasis has been given to international migration due to climate change. But there is a need to recognize the migration of such people within the countries also so that their problems can be addressed properly. Which of the following is the most rational inference from the above passage?

The passage repeatedly highlights gaps in understanding and recognition regarding climate change and migration. Analysis of Options: A) The world will not be able to cope with large scale migration of climate refugees: The passage points to challenges in providing protection and recognizing migrants, but it does not definitively state that the world "will not be able to cope." It focuses more on the current lack of frameworks and understanding. B) We must find the ways and means to stop further climate change: While stopping climate change is a long-term solution, the passage's immediate focus is on the consequences of climate change (migration) and the lack of a framework to deal with these migrants. It doesn't primarily infer the need to stop climate change itself. C) Climate change will be the most important reason for the migration of people in the future: The passage states climate change is "likely to expose a large number of people" to migration, but it does not claim it will be "the most important reason." This is an overstatement not directly supported by the text. D) Relation between climate change and migration is not yet properly understood: This is directly supported by several statements in the passage: "The international community is yet to recognize this new category of migrants," "There is no consensus on the definition and status of climate refugees," and most explicitly, "There are still gaps in understanding how climate change will work as the root cause of migration." The passage consistently emphasizes a lack of clarity, definition, and comprehensive understanding. Therefore, D is the most rational inference.
