- A, B
- B, A
- C, D
- B, C
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Industrial microbiology and biofertilizers.
Step 2: Meaning
Evaluating biological processes in soil enrichment and fermentation.
Step 3: Analysis
Biofertilizers enrich soil nutrient quality (A is correct). Anaerobic bacteria acting on cellulosic material produce methane, $CO_{2}$, and $H_{2}$ (B is correct). C is incorrect as they produce more than just hydrogen sulphide. D is incorrect as wine and beer production does not require distillation.
Step 4: Conclusion
Statements A and B are correct.
Final Answer: (1)
