Step 1
The nutrient broth was not boiled thoroughly on Day 1.
Answer
Option (C) provides the best explanation for the difference in results observed by the student compared to Pasteur’s. If the nutrient broth was not boiled thoroughly on Day 1, it may not have been sterilized adequately, allowing for microbial growth that could lead to different results. Pasteur's experiment was foundational in demonstrating the importance of sterilization in preventing contamination.
