Final answer:
The scientific name of the cow, Bos primigenius, corresponds to the genus and species categories in biological classification, which are represented in the Linnaean hierarchy by boxes A and B respectively.
Step-by-step explanation:
The name Bos primigenius represents the scientific classification of the cow at the genus and species level. The correct answer to the question is D. the genus and species names, which go in boxes A and B, respectively. In taxonomy, the genus is the category higher than the species and both together constitute the binomial nomenclature system that is used to uniquely identify species. For instance, in the classification of humans, our scientific name is Homo sapiens, where 'Homo' is the genus and 'sapiens' is the species.
The Linnaean system of classification categorizes living organisms in a hierarchical structure, starting with the domain and ending with the species. The hierarchal levels are: domain, kingdom, phylum, class, order, family, genus, and species. This system was developed by Carl Linnaeus, a Swedish botanist, zoologist, and physician in the 18th century, and has been the standard method for classifying organisms in biology.
