Which statement best describes natural immunity?

• A. It is solely inherited
• B. It is solely developed through vaccines
• C. It is partly inherited and partly developed through healthy living
• D. It is not influenced by living habits

Answer: (C)

Natural immunity comes from two intertwined sources: genetics and the influence of your environment and habits. Some parts of the immune system are inherited, shaping how your body initially responds to pathogens. At the same time, healthy living—good nutrition, regular exercise, adequate sleep, stress management, and avoiding harmful habits—supports and strengthens your immune system overall. This combined view is why the statement that natural immunity is partly inherited and partly developed through healthy living is the most accurate. It’s not solely about genetics, nor is it only about vaccines (which create a different, specific type of immunity), and living habits do impact immune function.
