What is the term used to describe the process of making an object germ-free?

1. Sterilization

2. Sanitization

3. Disinfection

4. Cleansing

The correct answer is: Sterilization

The correct term for making an object germ-free is sterilization. This process involves the destruction or removal of all forms of microbial life, including bacteria, viruses, fungi, and spores, from a surface or substance. Sterilization is often achieved using methods such as autoclaving, chemical sterilants, or radiation. Sanitization, while related, specifically reduces the number of microorganisms to a safe level as defined by public health standards, rather than completely eliminating them. Disinfection, on the other hand, eliminates many or all pathogenic microorganisms, except fungal spores, from inanimate objects. Cleansing refers to the physical removal of dirt, dust, and impurities, which may not necessarily involve killing or removing all germs. Thus, sterilization is the most precise term for achieving a germ-free state.
