Answer: (C)

Verified step by step guidance

1. Understand that a Safety Data Sheet (SDS) provides detailed information about the hazards, handling, and safety precautions of a chemical substance.
2. Recall that sodium hypochlorite (NaOCl) is commonly used as a disinfectant and bleach, and it is known for its chemical reactivity, especially as an oxidizing agent.
3. Recognize that sodium hypochlorite is not flammable, so it does not pose a fire risk, and it is reactive with acids, producing hazardous gases like chlorine.
4. Identify that the primary hazards listed in the SDS for sodium hypochlorite include its strong oxidizing properties and its potential to cause skin and eye irritation upon contact.
5. Conclude that the most accurate hazard description from the options is that sodium hypochlorite is a strong oxidizer and can cause skin and eye irritation.
