The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Assertion**: The assertion states that Alexander Fleming observed that Penicillium notatum inhibits the growth of staphylococci. This is true. Fleming discovered that the mold Penicillium notatum produced a substance that prevented the growth of bacteria, specifically staphylococci. 2. **Understanding the Reason**: The reason provided states that the inhibiting chemical was commercially extracted and its full potential was established by Alexander Fleming. This statement is partially true but misleading. While Fleming did discover penicillin, he did not commercially extract it or establish its full potential. This work was carried out later by scientists Howard Florey and Ernst Boris Chain. 3. **Evaluating the Relationship**: The assertion is true, but the reason is false. The reason does not correctly explain the assertion because it misattributes the commercial extraction and establishment of penicillin's potential to Fleming instead of the scientists who followed him. 4. **Conclusion**: Therefore, the correct answer is that the assertion is true, but the reason is false. ### Final Answer: - Assertion: True - Reason: False - Conclusion: Assertion is true but reason is false.
