What term describes the body's ability to resist and destroy pathogens and respond to infection?

• A. Immunity
• B. Antibiotics
• C. Carbohydrates
• D. Water

Answer: (A)

Immunity is the body's ability to resist and destroy pathogens and respond to infection. It involves fast, nonspecific barriers like the skin and immune cells that patrol for invaders, plus specialized adaptive responses that target specific pathogens and can remember them for quicker defense in the future. Antibiotics are medicines that treat infections by killing or inhibiting bacteria, but they are external aids, not the body's own defense. Carbohydrates provide energy for all bodily functions, including immune cells, and water supports hydration and overall function, but neither defines the body's defensive system.
