Explanation:
Aerobic, Anaerobic, and Facultative Bacteria
Bacteria are classified into three groups based on their oxygen requirements:
- Aerobic bacteria: These bacteria require oxygen to survive, grow, and reproduce. Aerobic bacteria are usually found in environments with high oxygen concentrations, such as the human body and the surface of the earth.
- Anaerobic bacteria: These bacteria cannot survive in the presence of oxygen. They require oxygen-free environments to grow and reproduce. Anaerobic bacteria are usually found in environments with low oxygen concentrations, such as deep sea vents, soil, and the human gut.
- Facultative bacteria: These bacteria can survive and grow in the presence or absence of oxygen. They can switch between aerobic and anaerobic metabolism depending on the oxygen availability. Facultative bacteria are usually found in environments with variable oxygen concentrations, such as soil, water, and the human gut.
The Incorrect Statement
The statement "none of these" is incorrect because it does not provide any information about the oxygen requirements of bacteria. The correct statement would be "all of these" because it includes all three types of bacteria: aerobic, anaerobic, and facultative.
Conclusion
In conclusion, bacteria are classified into three groups based on their oxygen requirements: aerobic, anaerobic, and facultative. Aerobic bacteria require oxygen to survive, anaerobic bacteria cannot survive in the presence of oxygen, and facultative bacteria can survive and grow in the presence or absence of oxygen. The statement "none of these" is incorrect because it does not provide any information about the oxygen requirements of bacteria. The correct statement would be "all of these" because it includes all three types of bacteria.

Here Aerobic bacteria are those which decompose the organic matter in the presence of o2 & anaerobic bacteria are those which decompose the organic matter in the absense of 02
Facultative bacteria works in presence of 02 as well as absence of 02 hence option d is right
Facultative bacteria works in presence of 02 as well as absence of 02 hence option d is right
