⭕ A. Anaerobic bacteria
⭕ B. Pathogenic bacteria
⭕ C. Non-pathogenic bacteria
⭕ D. Aerobic bacteria
📚 Explanation:
Aerobic bacteria are those microorganisms that require oxygen for their metabolic processes and survival. They use oxygen to oxidize substrates (like sugars and fats) to obtain energy.
🔹 These bacteria are commonly found in oxygen-rich environments like soil, water, and on surfaces of living organisms.
🔹 In contrast, anaerobic bacteria thrive in oxygen-free environments and may even be killed by oxygen exposure.

👉 Therefore, the correct answer is: D. Aerobic bacteria
Key Features of Aerobic Bacteria:
- Require oxygen to survive and grow
- Generate energy through aerobic respiration
- Commonly found in oxygen-rich environments like soil and water
- Play a crucial role in decomposition and nutrient cycling
- Used in wastewater treatment and composting
