The correct answer is: b) Millets, pulses, and oilseeds.
Red soils are well-drained and have a high content of iron oxide, which gives them their characteristic red color. They are also rich in nutrients, making them ideal for growing crops like millets, pulses, and oilseeds.
Millets are a type of cereal grain that is grown in tropical and subtropical regions. They are a good source of carbohydrates, protein, and fiber. Some common types of millets include sorghum, pearl millet, and finger millet.
Pulses are a type of legume that is grown for its edible seeds. They are a good source of protein, fiber, and iron. Some common types of pulses include lentils, beans, and peas.
Oilseeds are a type of seed that is grown for its oil content. They are a good source of protein, fiber, and vitamins. Some common types of oilseeds include soybeans, sunflower seeds, and canola seeds.
Wheat and barley are two types of cereal grains that are grown in temperate regions. They are a good source of carbohydrates, protein, and fiber. However, they are not well-suited to growing in red soils, as they prefer cooler climates and more fertile soils.
