The correct option is D Production of crops may be of lesser quantity than the demand.
Organic farming is the process of using natural methods in the production of crops. This is highly beneficial for the environment. For example, the pollution of the groundwater is reduced and food crops are free from chemicals.
However, there are certain shortcomings that an organic farmer should be able to manage. For example, production of crops may be delayed, as they have to grow in the natural environment. Also, the production may be in lesser quantities as it takes up a larger area of land for production.
Despite its shortcomings, organic farming is one of the primary solutions towards achieving sustainable development.
