The correct Answer is:
To solve the problem of matching the pairs correctly, we need to analyze each option provided in the question. Here’s a step-by-step breakdown: ### Step 1: Analyze Each Pair 1. **Cyanobacteria (1. Biopesticide)**: - Cyanobacteria are primarily known for their role in nitrogen fixation and as biofertilizers. They are not typically classified as biopesticides. - **Conclusion**: Incorrect match. 2. **Mycorrhiza (2. Solubilisation of phosphate)**: - Mycorrhiza refers to the symbiotic association between fungi (like Glomus) and plant roots. They enhance nutrient absorption, particularly phosphorus, by solubilizing it. - **Conclusion**: Correct match. 3. **Bacillus thuringiensis (3. Cry protein)**: - Bacillus thuringiensis (Bt) is known for producing Cry proteins, which are toxic to certain insects and are used as biopesticides. - **Conclusion**: Correct match. 4. **Single cell protein (4. Rhizobia)**: - Single cell protein refers to protein derived from microbial sources, while Rhizobia are nitrogen-fixing bacteria associated with legumes. They do not directly relate to single cell protein. - **Conclusion**: Incorrect match. ### Step 2: Summarize the Findings - The correct matches are: - Mycorrhiza → Solubilisation of phosphate (B → 2) - Bacillus thuringiensis → Cry protein (C → 3) ### Step 3: Identify Incorrect Matches - Cyanobacteria → Biopesticide (A → 1) is incorrect. - Single cell protein → Rhizobia (D → 4) is incorrect. ### Final Answer The pairs that are correctly matched are: - (b. Mycorrhiza, 2. Solubilisation of phosphate) - (c. Bacillus thuringiensis, 3. Cry protein)
