keywords: 

{'red soils': [0, 0, 0, 1], 'soil': [7, 0, 4, 7], 'ferric oxide content': [0, 0, 0, 1], 'colour': [11, 6, 13, 28]}

The correct answer is option 2, which states that statement 1 and statement 3 are correct.

Statement 1: The color of red soil in India is red due to the presence of ferric oxide. Ferric oxide is a compound that gives a reddish color to the soil.

Statement 2: This statement is incorrect. Red soils in India are deficient in lime, humus, and potash. They have lower fertility compared to other types of soil.

Statement 3: This statement is correct. Red soils are known for their porous nature and friable structure. This means that they have good drainage and are easy to work with, making them suitable for agriculture.

In summary, red soils in India get their color from ferric oxide (statement 1), but they are not rich in lime, humus, and potash (statement 2). However, they do have a porous and friable structure (statement 3).
