Answer 1

The Correct Option is B

Step 1: Understanding the Question:
This question tests knowledge of soil orders and their characteristics.

Step 2: Detailed Explanation:
Black cotton soil is commonly represented in the order Vertisols (B).
Vertisols are clay-rich soils that shrink and swell with changes in moisture.
They are found in regions with seasonal rainfall (e.g., Deccan Plateau in India).
Other soil orders:
- Alfisols (A): Found in humid regions (moderate fertility).
- Entisols (C): Recent soils (little horizon development).
- Aridisols (D): Desert soils.
Thus, black cotton soils are Vertisols.

Step 3: Final Answer:
Thus, black cotton soil is represented in the order Vertisols, which corresponds to option (B).
