2. Red and yellow soil: Red and yellow soils are formed due to weathering of rocks rich in iron and are commonly found in regions with a moderate climate. They are not described as clayey, deep, or impermeable, so this option is not correct.

3. Saline soil: Saline soil contains a high concentration of salts and is often found in arid and semi-arid regions. The given characteristics do not include any mention of salinity, so this option is not correct.

4. Black soil: Black soil, also known as regur soil, is rich in lime, iron, magnesia, and alumina. It is clayey, deep, and impermeable. Moreover, black soil is mainly found in Maharashtra, Madhya Pradesh, and Gujarat, as mentioned in the characteristics
