- Bacillus and Frankia
- Beijerinckia and Rhodospirillum
- Rhodospirillum and Azotobacter
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Beijerinckia is an aerobic nitrogen-fixing bacterium, while Rhodospirillum is anaerobic and photosynthetic. They represent typical examples of free-living nitrogen-fixers adapted to different oxygen conditions.
