Which of the following is a eukaryotic microorganism?

Explanation:
Eukaryotic microorganisms have cells with a true nucleus and membrane-bound organelles. Fungi fit this description, as their cells contain a nucleus and organelles like mitochondria, and they can be unicellular (yeasts) or multicellular (molds). In contrast, bacteria and archaea are prokaryotes, lacking a nucleus and most organelles. Viruses aren’t cells at all; they’re simple packages of nucleic acid within a protein coat and require a host cell to replicate. So, the organism that is a eukaryotic microorganism is fungi.
