Name the scientist who disproved the theory of spontaneous generation.

• A. Aristotle, Linnaeus, and Darwin
• B. Francesco Redi, Lazzaro Spallanzani, and Louis Pasteur
• C. Bentham and Hooker
• D. Mendel, Francis Crick, and Hugo de Vries

The scientist who played a crucial role in disproving the theory of spontaneous generation is Louis Pasteur. Along with Francesco Redi and Lazzaro Spallanzani, he conducted experiments that demonstrated that life does not arise spontaneously from non-living matter.

Key Contributors to the Disproof of Spontaneous Generation

• Francesco Redi: Conducted experiments with meat and maggots, showing that flies come from eggs, not spontaneously from meat.
• Lazzaro Spallanzani: Showed that microorganisms come from other microorganisms, not from spontaneous generation.
• Louis Pasteur: Used swan-neck flasks to demonstrate that microorganisms in the air contaminate sterile solutions, further debunking the theory.

Thus, the correct answer is B. Francesco Redi, Lazzaro Spallanzani, and Louis Pasteur.
