The correct Answer is:
To solve the matching question, we will analyze each item in Column I and find the correct corresponding item in Column II. ### Step-by-Step Solution: 1. **Identify Free-living Aerobic Nitrogen Fixers (A)**: - Free-living aerobic nitrogen-fixing bacteria are those that can fix nitrogen independently and require oxygen. - The correct example is **Azotobacter and Beijerinckia**. - **Match: A → iv. Azotobacter and Beijerinckia** 2. **Identify Anaerobic Nitrogen Fixers (B)**: - Anaerobic nitrogen-fixing bacteria do not require oxygen for their nitrogen-fixing process. - The correct example is **Rhodospirillum**. - **Match: B → v. Rhodospirillum** 3. **Identify Nitrogen-fixing Bacteria (C)**: - Nitrogen-fixing bacteria convert atmospheric nitrogen into ammonia. - The correct examples are **Anabaena and Nostoc**. - **Match: C → i. Anabaena and Nostoc** 4. **Identify Denitrifying Bacteria (D)**: - Denitrifying bacteria convert nitrates in the soil back into nitrogen gas, thus completing the nitrogen cycle. - The correct examples are **Pseudomonas and Thiobacillus**. - **Match: D → ii. Pseudomonas and Thiobacillus** 5. **Identify Nitrifying Bacteria (E)**: - Nitrifying bacteria convert ammonia into nitrites and then into nitrates. - The correct examples are **Nitrosomonas and Nitrosococcus**. - **Match: E → iii. Nitrosomonas and Nitrosococcus** ### Final Matches: - A → iv. Azotobacter and Beijerinckia - B → v. Rhodospirillum - C → i. Anabaena and Nostoc - D → ii. Pseudomonas and Thiobacillus - E → iii. Nitrosomonas and Nitrosococcus ### Correct Option: The correct option is **1st**.
