The correct Answer is:
To solve the question of matching the pairs correctly, we will analyze each option provided in the question and determine if they are correctly matched or not. ### Step-by-Step Solution: 1. **Analyze Option (a): "Cyanobacteria" - "Biopesticide"** - Cyanobacteria, also known as blue-green algae, are not used as biopesticides. They are primarily known for their role in nitrogen fixation and as a source of food (e.g., spirulina). - **Conclusion**: This pair is **incorrect**. 2. **Analyze Option (b): "Mycorrhiza" - "Solubilisation of phosphate"** - Mycorrhiza refers to the symbiotic association between fungi and plant roots. This relationship enhances the solubilization of phosphate, making it more available to plants. - **Conclusion**: This pair is **correct**. 3. **Analyze Option (c): "Bacillus thuringiensis" - "Cry protein"** - Bacillus thuringiensis (Bt) is a bacterium that produces a protein known as Cry protein, which is used as a biopesticide. It is effective against certain insect pests and is commonly used in genetically modified crops like Bt cotton. - **Conclusion**: This pair is **correct**. 4. **Analyze Option (d): "Single cell protein" - "Rhizobia"** - Single cell protein refers to protein derived from microbial sources, such as algae or fungi, and is not specifically related to Rhizobia. Rhizobia are bacteria that form symbiotic relationships with legumes to fix nitrogen, not typically associated with single cell protein production. - **Conclusion**: This pair is **incorrect**. ### Summary of Correctly Matched Pairs: - **Correct Matches**: - (b) Mycorrhiza - Solubilisation of phosphate - (c) Bacillus thuringiensis - Cry protein ### Final Answer: The pairs that are correctly matched are: - (b) Mycorrhiza - Solubilisation of phosphate - (c) Bacillus thuringiensis - Cry protein
