Select the correct statements regarding dissolved Oxygen and Biochemical Oxygen Demand.
(A) BOD is inversely related to dissolved oxygen.
(B) Low dissolved oxygen and high BOD lead to loss of aquatic life.
(C) High BOD leads to high dissolved oxygen.
(D) Both BOD and dissolved oxygen are indicator of health of a water body.
(E) Both BOD and dissolved oxygen are affected by amount of organic matter in the water body.
Choose the most appropriate answer from the options given below.

A, B, D and E only are the correct statements.
C is incorrect.
A. Biochemical oxygen demand (BOD) is a measure of the amount of oxygen consumed by microorganisms while decomposing organic matter in water. As the BOD increases, the demand for oxygen increases, leading to a decrease in dissolved oxygen levels.
B. Aquatic organisms rely on dissolved oxygen for their survival. When dissolved oxygen levels are low, it can lead to hypoxia or anoxia, causing stress or death to aquatic life.
C. High BOD leads to low dissolved oxygen. As the BOD increases, more oxygen is consumed during the decomposition process, resulting in a decrease in dissolved oxygen levels.
D. BOD and dissolved oxygen levels provide important information about the quality and health of a water body.
High BOD and low dissolved oxygen levels indicate poor water quality and potential pollution.
E. As the amount of organic matter increases, BOD levels rise, leading to a decrease in dissolved oxygen
levels as oxygen is consumed during decomposition.
