Complete answer:
Let’s discuss the options and find out the correct answer.
- Neurospora is a genus under the Ascomycete fungi. The meaning of the term Neurospora is “nerve spora”. One of the best species in this genus is Neurospora crassa. It belongs to the kingdom “Fungi” and phylum “Ascomycota”. The reason it is used as a genetic organism is it is easy to grow and possesses a haploid life cycle. Hence, option A is incorrect.
-Claviceps is a genus under the fungi species which is found in the ovaries of grasses and rye and many other similar plants. Claviceps purpurea is an ergot fungus that develops in the ears of rye. Hence, option B is incorrect.
-Penicillium is a genus under the ascomycetous fungi which is of great importance in the natural environment, in the spoilage of food and in the production of food and drugs. Few members of this genus produce penicillin which is used as a common antibiotic. Hence, option C is incorrect.
-Saccharomyces is a genus that includes species of yeasts. The meaning of saccharomyces is sugar fungus. Many members under this genus are important in the production of food. Another name for this genus is brewer’s yeast or baker’s yeast.
Hence, option D: Saccharomyces is the correct answer.

Note: Saccharomyces is a single-celled microorganism which is mainly found on or around the body. There are a lot of varieties of Baker’s yeast, the only difference between them is the moisture content.The choice is made by the cook depending upon the recipe which is to be prepared.
