Which of the following pairs of gases is mainly responsible for greenhouse effect A. Ozone and ammonia B. Oxygen and nitrogen C. Nitrogen and sulphur dioxide D. Carbon dioxide and methane
Option D. Relative contribution of various greenhouse gases to total global warming is ∙ CO2=60% ∙ CH4=20% ∙ CFC=14% ∙ N2O=6% ⇒ Therefore CO2 and CH4 are the major greenhouse gases. So, the correct answer is 'carbon dioxide and Methane'
