Pasteur's Germ Theory was published in which year?

• A. 1859
• B. 1861
• C. 1870
• D. 1865

Answer: (B)

1861 is the year Pasteur formally presented the germ theory, showing that tiny organisms are responsible for fermentation and disease rather than life arising spontaneously. His experiments, especially with the swan-neck flask, demonstrated that sterilized broth stays clear of microbes unless exposed to air carrying microorganisms, which provided direct evidence that germs cause fermentation and illness. This milestone moved science away from spontaneous generation and laid the foundation for modern microbiology and medical practices. Earlier work on fermentation existed, but the explicit publication of the germ theory itself is dated to 1861.
