Which one of the following is not an example of eukaryotic organism?

Result
Your answer: —  Â·  Correct: B
Explanation

Living organisms are classified into two broad categories based on cell structure: prokaryotes and eukaryotes. Eukaryotic organisms possess complex cells with a membrane-bound nucleus and specialized organelles. This group includes animals (such as human beings), plants, fungi (such as yeast), and protists [1]. In contrast, prokaryotic organisms lack a defined nucleus and membrane-bound organelles, with their genetic material residing in a nucleoid region. Bacteria and Archaea are the primary examples of prokaryotes. While yeast is a unicellular organism, it is a fungus and thus eukaryotic. Human beings and plants are multicellular eukaryotes. Therefore, bacteria are the only organisms listed that are not eukaryotic, as they are fundamentally prokaryotic in nature.
