Answer is Right!
Answer is Wrong!
The correct answer is C. Killing of disease bacteria.
Disinfection is a process that kills or inactivates disease-causing microorganisms in water. It does not remove turbidity or hardness. Complete sterilization is not possible, as some microorganisms may be resistant to disinfection.
There are many different methods of disinfection, including chlorination, chloramination, ozone treatment, ultraviolet light treatment, and filtration. The most effective method of disinfection will vary depending on the type of water being treated and the level of contamination.
Disinfection is an important step in ensuring the safety of drinking water. It helps to protect people from waterborne diseases such as cholera, typhoid, and dysentery.
