Solution

The correct option is D Penicillium notatum
  • Alexander Fleming was working on a Bacterial culture of Staphylococcus to studying the action of lysozyme and its role in the fighting of the infection.
  • While he was working with the culture he noticed that the bacterial culture's growth is inhibited due to the growth of fungal infection on it.
  • The fungus that infected the culture was Penicillium notatum , whose secretion was later to be discovered as antibiotic penicillin.
  • So the answer Penicillium notatum is correct.
