{'soil': [7, 0, 4, 7], 'laterite soil': [3, 0, 0, 0], 'black soil': [2, 0, 0, 1], 'saline soil': [0, 0, 0, 1], 'yellow soil': [0, 0, 0, 2], 'madhya pradesh': [16, 0, 16, 28], 'maharashtra': [1, 0, 0, 1]}

The correct answer is option 4: Black soil.

The given characteristics of the soil help us identify its type. Let`s examine each option to understand why option 4 is the correct answer:

1. Laterite soil: Laterite soil is typically found in tropical regions and is characterized by its reddish color and high concentration of iron oxide. It is not described as being rich in lime or alumina, so this option is not correct.

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
