Information: - In biology, a taxon (plural taxa; back-formation from "taxonomy") is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is not uncommon, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. - Sea snail is a common name for snails that normally live in saltwater, in other words marine gastropods. The taxonomic class Gastropoda also includes snails that live in other habitats, such as land snails and freshwater snails. Many species of sea snails are edible and exploited as food sources by humans. - Caenogastropoda (from Ancient Greek "caeno-" meaning "recent") is a taxonomic clade, a large diverse group which are mostly sea snails and other marine gastropod mollusks, but also includes some freshwater snails and some land snails. - Architaenioglossa is a taxonomic group of snails which have gills and often an operculum . They are primarily land and freshwater gastropod mollusks within the clade Caenogastropoda . This '' informal group '' has been shown to be polyphyletic in a study by Harasewych et al. , published in 1998 . - A land snail is any of the numerous species of snail that live on land, as opposed to sea snails and freshwater snails. "Land snail" is the common name for terrestrial gastropod mollusks that have shells (those without shells are known as slugs). However, it is not always easy to say which species are terrestrial, because some are more or less amphibious between land and freshwater, and others are relatively amphibious between land and saltwater. - Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from wasp-like ancestors in the Cretaceous period, about 99 million years ago and diversified after the rise of flowering plants. More than 12,500 of an estimated total of 22,000 species have been classified. They are easily identified by their elbowed antennae and the distinctive node-like structure that forms their slender waists. - A clade (from , "klados", "branch") is a group of organisms that consists of a common ancestor and all its lineal descendants, and represents a single "branch" on the "tree of life". After reading the paragraphs above, we are interested in knowing the entity with which 'architaenioglossa' exhibits the relationship of 'taxon rank'. Find the answer from the choices below. Choices: - branch - class - family - form - group - order - species
