Explanation:
Eubacteria, unlike Archaea, generally live in less extreme environments. They are unicellular, prokaryotic, lack nuclei, and unlike many Archaea, cannot live without oxygen.
Organisms in the Kingdom Eubacteria, also known as the domain Bacteria, are unicellular prokaryotic organisms without nuclei.
Compared to organisms in the domain Archaea, which often thrive in extreme environments, organisms in Kingdom Eubacteria generally live in less extreme environments, making option 'B' the correct answer to your question.
They are found in variety of habitats and can adapt to a broad range of conditions, but they do not typically favor the same harsh, extreme environments that many Archaea do.
They also lack the adaptation to live without oxygen seen in some prokaryotes, like certain Archaea.
