Correct Answer:
C. Penicillin
Explanation:
Penicillin was the first true antibiotic, discovered by Alexander Fleming at St. Mary's Hospital in London in 1928. He observed that a mold called Penicillium notatum had contaminated a petri dish of Staphylococcus bacteria and was preventing the bacteria from growing around it. This accidental finding revolutionized medicine by providing a powerful tool to treat bacterial infections that were previously fatal. Fleming eventually shared the 1945 Nobel Prize in Medicine for this breakthrough, which paved the way for the development of modern antibiotics.
