Taxonomy is the practice of classifying and naming living things into categories or groups based on similar characteristics. In 1758, biologist Carl Linnaeus created a system for classification that was used for hundreds of years. He gave each species two names (for example, Homo sapiens), showing their genus and species. He then grouped each genus into families, then orders, then classes, then phyla, and finally into two kingdoms: plants and animals. Linnaeus based kingdom classification on whether the organism moved or not. This system changed very little until the 1960's, when scientist R.H. Whittaker proposed a six Kingdom classification system where living things were grouped as plants, animals, fungi, protists, or monera (eubacteria and archeobacteria).

The correct answer is:
B. the presence of a nucleus surrounded by a membrane
This statement describes a key characteristic used to separate the bacteria kingdom (which consists of prokaryotic organisms that lack a membrane-bound nucleus) from the other kingdoms (plants, animals, fungi, and protists), which are composed of eukaryotic cells that do have a membrane-bound nucleus.
