Q. The gas, which is emitted in the paddy fields and increases the earth's temperature is

1. Nitrogen
2. Carbon dioxide
3. Carbon monoxide
4. Methane

Answer: Methane

A paddy field is a flooded parcel of arable land used for growing semiaquatic crops, most notably rice and taro.
Paddy fields account for around 20% of human-related emissions of methane — a potent greenhouse gas. Farmers normally flood rice fields throughout the growing season, meaning that methane is produced by microbes underwater as they help to decay any flooded organic matter.
