Answer 2

Answer:

The correct option is (b) Water

Explanation:

BOD determines the health of water and what it defines is Oxygen level in the water system. BOD is the biological method used for the measurement of the total amount of dissolved oxygen (DO) used by microbes in the biological process of metabolizing organic molecules present in water.

The amount of oxygen required or requested by aerobic bacteria to break down the organic matter contained in a certain sample of water at a specific temperature and time period is known as biochemical oxygen demand (BOD).

• The higher the BOD of a water body or water sample, the more polluted it is. The rise in organic matter can be attributed to environmental variables, although it is most commonly attributed to anthropogenic sources such as pollution.
• BOD is used to assess the quality of water. Determining the amount of organic matter in a body of water and its impact on the ecosystem and aesthetics of the water body is an important aspect of water quality management.
