Cevap
The correct answer is A. Chlorine.Chlorine is commonly used to disinfect water sources. It is a powerful oxidizing agent that can effectively kill a wide range of microorganisms, including bacteria, viruses, and protozoa. Chlorine is added to water in the form of chlorine gas or chlorine compounds, such as sodium hypochlorite, to ensure the disinfection of the water.Sodium hypochlorite (option B) is a chemical compound that contains chlorine and is also used as a disinfectant. However, it is not the primary disinfectant used in water treatment.Phenolic compounds (option C) are a group of chemicals that are used as disinfectants, but they are not commonly used for water disinfection.Etidium bromide (option D) is a DNA-binding dye that is used as a staining agent in molecular biology, but it is not a disinfectant.Therefore, the correct answer is A. Chlorine.
