Which of the following is the definition of chemical disinfection?

Chemotherapy
Chronic
Circulatory system
Chemical substances used to kill or deactivate pathogenic microorganisms

The correct answer is: Chemical substances used to kill or deactivate pathogenic microorganisms

The correct definition of chemical disinfection refers to chemical substances that are specifically designed to kill or deactivate pathogenic microorganisms. Chemical disinfection is a crucial process in maintaining hygiene and preventing the spread of infections in healthcare settings. These substances can include disinfectants and antiseptics that are applied to surfaces or skin to eliminate harmful bacteria, viruses, and fungi, ensuring a safe environment for patients and health care workers. The other options do not relate to the definition of chemical disinfection. Chemotherapy pertains to cancer treatment using chemicals to destroy cancer cells, while "chronic" refers to a condition or disease that persists over a long period of time, generally involving symptoms that are less severe but long-lasting. The circulatory system is a standalone biological system responsible for the transportation of blood, nutrients, and other substances throughout the body, which does not relate directly to the concept of disinfection.
