Solution
The correct option is C Bacteria (Staphylococcus)
In 1928, Alexander Fleming was investigating the properties of Staphylococci. One day, he observed that the culture of Staphylococci was contaminated with fungus and that colonies of the culture surrounding the fungus had been destroyed.
Fleming grew the mold in a pure culture and found that it produce a substance that killed a number of disease-causing bacteria. He identified the mold (fungus) as being from the Penicillium genus and named the substance it released Penicillin. He investigated its positive antibacterial effect on many organisms and noticed that it affected bacteria such as Staphylococci and many other Gram-positive pathogens that cause scarlet fever, pneumonia, meningitis, diphtheria but not typhoid fever caused by Gram-negative bacteria.Therefore, the correct answer is option B.
