Which description best matches natural immunity?

• A. Immunity that is acquired solely through vaccination.
• B. Immunity that is entirely inherited at birth.
• C. Immunity that is partly inherited and partly developed through healthy living.
• D. Immunity that lasts only a few days.

Answer: (C)

Natural immunity involves defenses you’re born with plus those that develop as you live and encounter microbes, not through vaccination. It includes innate barriers and immune responses that exist from birth, and it can be refined by factors in daily life like good nutrition, sleep, exercise, and reasonable exposure to the environment. So, immunity being partly inherited and partly developed through healthy living captures both the genetic baseline and the environmental influences that shape how your immune system functions over time. Vaccination gives artificial immunity, immunity isn’t solely inherited at birth, and natural immunity isn’t restricted to lasting only a few days.
