The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Humification**: Humification is a process that occurs during the decomposition of organic matter in the soil. It involves the transformation of decomposed organic materials into a stable form known as humus. 2. **Decomposition Stages**: The decomposition process consists of several stages: - **Fragmentation**: Large organic particles are broken down into smaller pieces. - **Leaching**: Water-soluble substances are washed away, and some nutrients may be lost to deeper soil layers. - **Catabolism**: Microorganisms, such as bacteria and fungi, further break down the organic material into simpler compounds. 3. **Formation of Humus**: After these stages, the remaining organic matter undergoes humification, which results in the formation of humus. Humus is characterized by its dark color and colloidal nature. 4. **Identifying the Correct Option**: The question asks what humification results in the formation of. The options provided are: - A) Colloidal basic substance - B) Acidic dark colored substance - C) Amorphous light colored substance - D) Light colored colloidal substance 5. **Analyzing the Options**: - Option A is incorrect because humus is not a basic substance. - Option B is correct as humus is indeed an acidic, dark-colored substance. - Option C is incorrect because humus is not light-colored. - Option D is also incorrect for the same reason as C. 6. **Conclusion**: Based on the analysis, the correct answer is **B) Acidic dark colored substance**. ---
