• B. Sodium hypochlorite (NaClO)

• D. Sodium bicarbonate (NaHCO_3)

Answer: (B)

Verified step by step guidance

1. Understand that household bleach and many cleaners rely on a chemical that acts as a disinfectant and oxidizing agent to kill bacteria and remove stains.
2. Recall that hydrogen peroxide (H\_2O\_2) is a common disinfectant but is not the main active ingredient in typical household bleach.
3. Recognize that ammonium chloride (NH\_4Cl) is primarily used as a fertilizer or in some cleaning agents but is not the main bleaching agent.
4. Know that sodium bicarbonate (NaHCO\_3), also known as baking soda, is used for mild cleaning and deodorizing but does not have strong bleaching properties.
5. Identify sodium hypochlorite (NaClO) as the main active component in bleach, responsible for its strong oxidizing and disinfecting properties.
