The correct answer is: c) Agroforestry.
Agroforestry is a type of farming that integrates trees and shrubs with crops and livestock. It is a sustainable agricultural system that can help to improve soil fertility, reduce erosion, and increase biodiversity.
Monoculture is a type of farming that focuses on growing a single crop. This can be harmful to the environment because it can lead to soil erosion, nutrient depletion, and the loss of biodiversity.
Permaculture is a system of agricultural and social design principles centered on simulating or directly utilizing the patterns and features observed in natural ecosystems. It has many similarities to agroforestry, but it also includes a focus on social and economic sustainability.
Organic farming is a type of agriculture that uses natural methods to grow crops and raise livestock. It does not use synthetic pesticides, herbicides, or fertilizers. Organic farming can be beneficial for the environment, but it can also be more expensive than conventional farming.
