These sanitizers are useful storage containers, but do not disinfect or sterilize.

• A. Steam
• B. Alcohol
• C. UV
• D. Microwave

Answer: (C)

The concept here is that some devices are designed as storage containers that use a sanitizing method, rather than being true disinfectants or sterilizers. A UV sanitizing box sits items inside and exposes their surfaces to ultraviolet-C light to reduce surface microbes. But because the light must reach every surface directly, shadows, crevices, and sealed areas may not be treated, and UV alone does not guarantee complete disinfection or sterilization. So the container itself isn’t disinfecting or sterilizing in the same way steam or chemical disinfection would; it’s a storage aid that can help reduce contamination when used correctly, not a standalone disinfection method. Steam, alcohol, and microwaves are methods that, when applied properly, actively disinfect or sterilize items rather than just store them. They’re not storage containers, which is why ultraviolet—as a storage-container option that provides limited sanitizing effect—fits the described scenario.
