The correct statement regarding the taxonomic system is:
c the current taxonomic system is based on the Linnaean classification system.
The Linnaean system, developed by Carl Linnaeus, is the foundation for modern taxonomy, which classifies living organisms into a hierarchy of categories (such as kingdom, phylum, class, order, family, genus, and species).
The other statements are not true: a. Not all current living species have been cataloged. b. Charles Darwin contributed to the understanding of evolution and natural selection but was not the primary creator of the current taxonomic system. d. Not all past, extinct species have been cataloged.
