The correct answer is: a) Rice-Fish farming.
Rice-fish farming is a traditional agricultural practice that combines the cultivation of rice with the rearing of fish. It is a sustainable and efficient way to produce food, and it has been practiced in many parts of the world for centuries.
In rice-fish farming, the rice paddies are flooded with water, and fish are introduced into the water. The fish eat the pests and weeds that would otherwise damage the rice crop, and they also fertilize the water with their waste. The rice plants provide the fish with shade and shelter, and they also help to filter the water.
