The correct option is D Show most simple metabolic diversity
Eubacteria are organisms belonging to kingdom Monera and lack a nuclear membrane and membrane bound organelles. Despite the lack of internal compartmentalization, bacterial metabolism is complex and is far more diverse than eukaryotic metabolism. Eubacteria have cell wall which is composed of peptidoglycan. These organisms are very simple in structure. The eubacteria are the most abundantly found organisms in this world and most of them are heterotrophs. Thus option d is incorrect.
