Which product would likely be used to prevent the spread of germs on environmental surfaces?

The product that is commonly used to prevent the spread of germs on environmental surfaces is a disinfectant. Disinfectants are formulated specifically to eliminate or reduce harmful microorganisms on surfaces, making them essential in maintaining hygiene and safety in environments such as salons and spas. They work by killing bacteria, viruses, and fungi, thereby minimizing the risk of infections and cross-contamination among clients and staff.

Other products mentioned, such as perfume, moisturizer, and conditioner, serve different purposes. Perfumes are designed for fragrance and have no germ-killing properties. Moisturizers are intended for skin hydration and not for disinfection, while conditioners are primarily used to improve the texture and manageability of hair. Therefore, only a disinfectant fits the need for germ prevention on surfaces.
