Answer: (B)

Verified step by step guidance

1. Understand the historical context: Louis Pasteur and John Tyndall were prominent figures in the 19th century who contributed significantly to microbiology and the understanding of microorganisms.
2. Recognize Pasteur's contributions: He is well-known for his experiments that disproved the theory of spontaneous generation, which posited that microorganisms could arise from non-living matter.
3. Identify Tyndall's role: John Tyndall conducted experiments that supported Pasteur's findings, further disproving spontaneous generation by demonstrating that microorganisms in the air could be eliminated by heat.
4. Consider the options given: Evaluate each option based on historical facts. Pasteur and Tyndall's work primarily focused on disproving spontaneous generation rather than developing antiseptic surgery, discovering wine spoilage causes, developing vaccines, or isolating bacteria.
5. Conclude based on evidence: The correct answer is that Pasteur and Tyndall worked together to disprove that microorganisms could arise from non-living matter, aligning with their historical contributions to microbiology.
