The Correct Option is B
Solution and Explanation
E. coli is commonly found in the intestines of warm-blooded animals, including humans, and is often used as an indicator of fecal contamination in water. The presence of E. coli in water indicates the potential presence of fecal matter and the possible presence of harmful pathogens associated with fecal contamination. It is an important marker for assessing water quality and safety.

Water Pollution
- Water pollution means the contamination of water bodies such as seas, lakes, rivers, aquifers, oceans, and groundwater caused majorly due to inhuman activities with industrial and agricultural effluents. It is the change of chemical, biological, or physical properties of water that will result in a destructive consequence for living organisms.
- Portable water is considered safe for human and animal consumption as well as used for drinking, cooking, crop irrigation, washing, etc,. Nowadays, chemicals, bacteria, and other pollutants are also influencing this. It adversely acts on all the living forms, directly or indirectly depending upon the source. The effects of water pollution can be felt for years to come.
