Which list names the five kingdoms?

• A. Eubacteria, Archaebacteria, Protista, Plants, Animals
• B. Eubacteria, Archaebacteria, Protists, Fungi, Animals
• C. Eubacteria, Archaebacteria, Protists, Plants, Animals
• D. Archaebacteria, Eubacteria, Protists, Plants, Animals

Answer: (C)

In the five-kingdom view of classification, life is grouped into five broad kingdoms: Eubacteria, Archaebacteria, Protists, Plants, and Animals. The two bacterial lineages are treated as separate kingdoms because of major differences in biochemistry and genetics, while Protists cover diverse single-celled and simple multicellular eukaryotes, Plants are multicellular photosynthetic organisms, and Animals are multicellular organisms that ingest other organisms. The listed set matches this traditional five-kingdom framework, using the standard plural form Protists, which is why it’s the correct choice. The other options either use a nonstandard singular form or differ in naming, but the essential five groups shown here are the ones recognized in this system.
