Question

why should you never mix two or more disinfectant products together? it will smell bad they are not as effective can cause the production of lethal gases rewatch

Explanation:

Mixing different disinfectant products can lead to chemical reactions. For example, mixing bleach (a common disinfectant) with ammonia - based cleaners can produce chloramine gases, and mixing bleach with acidic cleaners can produce chlorine gas, both of which are lethal. The option "It will smell bad" is a very minor and non - critical issue compared to the production of lethal gases. The option "They are not as effective" is also incorrect as the main danger is not reduced effectiveness but the production of dangerous substances.

Answer:

C. Can cause the production of lethal gases
