Question

Options
Methane
Carbon dioxide
Carbon monoxide
Ammonia
Solution
Ammonia
Explanation:
The gases which are transparent to solar radiation but retain and partially reflect back long-wave heat radiations are called greenhouse gases. Greenhouse gases are essential for keeping the earth warm and hospitable. Gases like carbon dioxide (CO2), methane (CH4), chlorofluorocarbons (CFCs), nitrous oxide (N20), carbon monoxide (CO), etc. are considered greenhouse gases. Ammonia is not a greenhouse gas and serves as a precursor of food and a building block of medicines.
