Q3 / 90 · JEE Main 2016 (09 Apr Online) · Chemistry

BOD stands for:

A
Bacterial Oxidation Demand
B
Biological oxygen demand
C
Biochemical oxygen demand
Correct answer
D
Both A and B

Solution

Biochemical Oxygen Demand (BOD) is also called Biological Oxygen Demand.

It is the amount of dissolved oxygen needed (i.e. demanded) by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period

Hence, the correct answer is option: 'D'.
