Biological Oxygen Demand (BOD) indicates:
Show Hint
BOD: oxygen required for organic matter decomposition.
Measures organic pollution in water.
Measures organic pollution in water.
Updated On: Aug 18, 2026
- Oxygen concentration of effluent
- Extent of inorganic matter
- Amount of oxygen required to stabilize the effluent
- 90% of oxygen required for 100% stabilization of effluent
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
BOD is a measure of water quality.
It indicates the organic pollution level.
Step 2: Key Formula or Approach:
No specific formula.
Need to understand the definition of BOD.
Step 3: Detailed Explanation:
BOD indicates the amount of oxygen required to stabilize the effluent.
It measures the oxygen consumed by microorganisms during decomposition of organic matter.
It does not indicate oxygen concentration.
It does not measure inorganic matter.
Thus, BOD is the amount of oxygen required.
Step 4: Final Answer:
BOD indicates the amount of oxygen required to stabilize the effluent.
Hence, the correct option is (C).
