Answer:
The correct answer is -a common characteristic (in a logical manner)
Step-by-step explanation:
The six kingdom classification is given by Woese et al 1977, the basis of this classification was the shared characteristic of organisms. These common characteristics include more than one character such as cell type ( prokaryotic or eukaryotic), type of nutrients (autotrophs, heterotrophs), type of reproduction, homologous or analogous organs, habitat, and many more.
All these traits or characters helped in grouping organisms in a logical manner and is one of the most acceptable classifications.
Thus, the correct answer is -a common characteristic (in a logical manner)
