Correct Answer:- B (2 Only).
Option 1 is wrong due to inorganic waste, it will be a Organic Waste.
Biochemical oxygen demand (BOD), the amount of dissolved oxygen used by microorganisms in the biological process of metabolizing organic matter in water. The more organic matter there is (e.g., in sewage and polluted bodies of water), the greater the BOD; and the greater the BOD, the lower the amount of dissolved oxygen available for higher animals such as fishes. The BOD is therefore a reliable gauge of the organic pollution of a body of water. One of the main reasons for treating wastewater prior to its discharge into a water source is to lower its BOD—i.e., reduce its need of oxygen and thereby lessen its demand from the streams, lakes, rivers, or estuaries into which it is released.

Which of the following statements is /are correct about the Biochemica...
• Statement 1 is incorrect: BOD is the amount of dissolved oxygen needed by bacteria in decomposing the organic wastes present in water.
Biochemical Oxygen Demand (BOD)
• Water pollution by organic wastes is measured in terms of Biochemical Oxygen Demand (BOD).
• BOD is the amount of dissolved oxygen needed by bacteria in decomposing the organic wastes present in water. It is expressed in milligrams of oxygen per liter of water.
• The higher value of BOD indicates the low DO content of water.
• Since BOD is limited to biodegradable materials only. Therefore, it is not a reliable method of measuring the pollution load in the water.
Chemical Oxygen Demand (COD)
• It is a slightly better mode used to measure pollution load in the water.
• It is the measure of oxygen equivalent of the requirement of oxidation of total organic matter (i.e. biodegradable and non-biodegradable) present in water.
