A
A protist such as an amoeba.
B
A plant cell such as Elodea.
C
A bacterial cell such as Streptococcus.

Explanation: 

Detailed explanation-1: -Eukaryotes are the organisms which have membrane bound cell organelles as well as membrane bound nucleus. All the kingdoms except kingdom monera are eukaryotes.

Detailed explanation-2: -Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane. Features that distinguish a bacterial cell from a eukaryotic cell include the circular DNA of the nucleoid, the lack of membrane-bound organelles, the cell wall of peptidoglycan, and flagella.

Detailed explanation-3: -Bacteria are prokaryotic and unicellular organisms. The cell wall of bacteria is made up of peptidoglycan layer, and they lack membrane-bound organelles. The bacterial cell has a simpler organisation of structure. Hence, the given statement is false as bacteria are not eukaryotic organisms.

Detailed explanation-4: -All animals, plants, fungi, and many unicellular organisms, are eukaryotes.
