The correct answer is: A. Nitrous oxide.
Nitrous oxide is a greenhouse gas that is produced from the agricultural fields. It is produced by the breakdown of organic matter in the soil, and by the use of nitrogen fertilizers. Nitrous oxide is a powerful greenhouse gas, and it is estimated that it is responsible for about 5% of the greenhouse gas emissions that are caused by human activity.
Ammonia is a gas that is produced by the breakdown of proteins in the soil. It is also produced by the use of ammonia fertilizers. Ammonia is not a greenhouse gas, but it can contribute to the formation of ground-level ozone, which
is a greenhouse gas.Sulphur dioxide is a gas that is produced by the burning of fossil fuels. It is also produced by the smelting of metals. Sulphur dioxide is a greenhouse gas, but it is not as powerful as nitrous oxide or methane.
Arsine is a gas that is produced by the breakdown of organic matter in the soil. It is also produced by the use of arsenic-based pesticides. Arsine is not a greenhouse gas, but it is a toxic gas.
In conclusion, the correct answer
is: A. Nitrous oxide. Nitrous oxide is a greenhouse gas that is produced from the agricultural fields. It is produced by the breakdown of organic matter in the soil, and by the use of nitrogen fertilizers. Nitrous oxide is a powerful greenhouse gas, and it is estimated that it is responsible for about 5% of the greenhouse gas emissions that are caused by human activity.
