Explanation:
The anaerobic respiration that is respiration which is involved in producing energy molecules like ATP without oxygen evolved earlier than aerobic respiration.
The anaerobic respiration undergoes glycolysis which produces pyruvic acid form lactic acid, ethanol, and very low amount of ATP. This anaerobic respiration is known as fermentation.
The fermentation produces a very low amount of ATP that is only 2 molecules but the amount is sufficient for the simple organisms to survive therefore the fermentation is still performed by the organisms.
The correct answer is a eukaryote. While it would be an impulse to answer prokaryote since the first thing that will come to our minds if we deal with a microorganism that thrives in extreme environments (i.e. hot thermal vents) will be archea, which are prokaryotes. But in this case, it is clearly specified that the single-celled organism has a nucleus which is the characteristic feature of eukaryotes.
Bacteria is incorrect as bacteria are prokaryotes. Plant is incorrect as all plants are multicellular organisms.
