The scientist associated with the germ theory of disease is ______.

• A. Charles Darwin
• B. Isaac Newton
• C. Albert Einstein
• D. Louis Pasteur

Answer: (D)

Germ theory of disease holds that many illnesses are caused by microscopic organisms. Louis Pasteur contributed crucial evidence by showing microbes are responsible for fermentation and can contaminate sterile solutions, which helped establish that disease can be caused by microorganisms. He also debunked spontaneous generation with his swan-neck flask experiments, demonstrating that germs come from the air rather than appearing from nowhere. His work led to practical advances like pasteurization to kill pathogens and vaccines, shaping modern medicine. The other scientists are known for different breakthroughs: Darwin for evolution, Newton for gravity and motion, Einstein for relativity.
