Correct answer: D. Herbert Copeland
- A. John Hogg
- B. Ernst Haeckel
- C. Margulis and Schwartz
- D. Herbert Copeland
Explanation
Herbert Copeland proposed a separate kingdom, Monera, for prokaryotic organisms such as bacteria, separating them from the eukaryotic protists. Haeckel introduced Protista but did not make this specific separation, so students may choose b because he is strongly associated with early kingdom classification.
