Answer: (B)

Sodium hypochlorite is commonly used for emergency disinfection of small water volumes because of its effectiveness, ease of use, and immediate availability in most settings. It is a liquid form of chlorine that can be precisely dosed, making it suitable for quickly treating water to render it safe for drinking. Additionally, sodium hypochlorite is readily available in household bleach, which many people have access to during emergencies. Its rapid action against a wide range of pathogens, including bacteria, viruses, and protozoa, ensures that water can be disinfected effectively in urgent situations. When used correctly, sodium hypochlorite can provide a straightforward and efficient solution for emergency disinfection needs.
