The correct Answer is:
To solve the matching question between Column A and Column B, we will analyze each item in Column A and find its corresponding match in Column B step by step. ### Step-by-Step Solution: 1. **Identify the first item in Column A: "Ladybird"** - Ladybirds are beetles that are known for their role in biological control, specifically targeting pests like aphids. - **Match:** Ladybird (i) matches with Aphids (C). 2. **Identify the second item in Column A: "Mycorrhiza"** - Mycorrhiza refers to a symbiotic association between fungi (specifically from the genus Glomus) and plant roots. - **Match:** Mycorrhiza (ii) matches with Glomus (D). 3. **Identify the third item in Column A: "Biological control"** - Biological control refers to the use of living organisms, such as Trichoderma, to manage pest populations, particularly pathogenic fungi. - **Match:** Biological control (iii) matches with Trichoderma (B). 4. **Identify the fourth item in Column A: "Biogas"** - Biogas is produced by methanogens, which include Methanobacterium. - **Match:** Biogas (iv) matches with Methanobacterium (A). ### Summary of Matches: - (i) Ladybird - (C) Aphids - (ii) Mycorrhiza - (D) Glomus - (iii) Biological control - (B) Trichoderma - (iv) Biogas - (A) Methanobacterium ### Final Answer: The correct answer is **B.
