Final answer:
The smallest and most significant taxon in the Linnaean classification system is the species, which is the option B from the choices provided.
Step-by-step explanation:
The smallest and most significant taxon in the Linnaean system of classification is species. The species grouping is the most specific and exclusive, denoting organisms that can interbreed to produce fertile offspring. This system categorizes living organisms into a hierarchical structure that includes larger, more inclusive categories such as genus, family, order, class, phylum, kingdom, and domain at the broadest level. Each ascending category groups together entities that share more general characteristics, with species at the base of this hierarchy as the most detailed classification.
