Solution

The correct option is C N2O

Explanation:

Agriculture is a major source of greenhouse gas (GHG) emissions. Chemical fertilizers, pesticides and animal waste from agriculture account for 60% of global anthropogenic emissions of methane (CH4) and 70% of nitrous oxide (N2O). About 90% of water in the atmosphere is produced by evaporation from the water bodies, while the rest 10% comes from transpiration from plants. Anthropogenic activities such as the burning of oil, coal and gas, as well as deforestation, are the primary cause of the increased CO2 concentrations in the atmosphere.
