Explanation:

Question 16

The body's first line of defense against infection includes physical and chemical barriers. Healthy skin is a primary physical barrier. Body secretions (like mucus) are also part, but skin is the first. White blood cells are part of the second line (innate immune response), and antitoxins are part of adaptive immunity. So the best answer is a.

Cleaning tools/instruments: Soap and water is a basic, acceptable way to clean (remove debris) before disinfection/sterilization. Supersonic units are for specific cleaning, cleaning solvents may be harsh, boiling for 5 minutes may not be sufficient for all tools. So c is correct.

A reaction due to extreme sensitivity to normally harmless substances is an allergy. Infection is from pathogens, disease is a broader term, parasite is an organism. So a is correct.

Answer:

a. healthy, uncompromised skin
