Step-by-Step Solution & Explanation
### **Official Solution & Concept Analysis (GATE BT 2022 Q.23)**
**1. Governing Concept**:
- **Topic**: Industrial Microbiology & Fermentation Products
- Matching industrial microbial products with producing microorganisms:
- Citric acid $\rightarrow$ *Aspergillus niger*
- Penicillin $\rightarrow$ *Penicillium chrysogenum*
- Streptomycin $\rightarrow$ *Streptomyces griseus*
- Glutamic acid $\rightarrow$ *Corynebacterium glutamicum*
- Perfectly matches Option (D) in the official GATE BT 2022 key.
**2. Option Analysis**:
- **Option (A) is INCORRECT**: Misassigns citric acid to bacterial fermentation.
- **Option (B) is INCORRECT**: Misidentifies penicillin producer.
- **Option (C) is INCORRECT**: Inverts fungal and actinomycete products.
- **Option (D) is CORRECT**: Standard industrial microbiology matching.
**3. Final Answer**:
- **Correct Choice**: **D**
