Intensive farming is defined by which of the following?

Intensive farming is characterized by high density of crops combined with high inputs of resources such as fertilizers, pesticides, water, and labor. This method is designed to maximize productivity on a given area of land, often leading to higher yields compared to extensive farming practices, which may use fewer inputs and cover larger areas with lower crop densities.

The rationale behind intensive farming is to efficiently produce a significant quantity of food or other agricultural products in a limited space, thereby making the most of available resources. This approach is commonly employed in modern agriculture, particularly in regions with high population densities where there is a strong demand for food supply.

In contrast, the other options accommodate farming methodologies focused on lower inputs or lower crop densities, which do not align with the definition of intensive farming. Therefore, the high density and high inputs distinguish intensive farming as a productive, resource-intensive system aimed at maximizing agricultural output.
