Swedish botanist; author of Systema Naturae; father of taxonomy

• A. Charles Darwin
• B. Carolus Linnaeus
• C. Gregor Mendel
• D. Louis Pasteur

Answer: (B)

Taxonomy and the formal system for naming living things are being tested. Carolus Linnaeus, a Swedish botanist, is the figure described: he created binomial nomenclature, giving every species a two-part name (genus and species) and began the structured classification that organizes life into a hierarchy. His work Systema Naturae propelled this framework, providing a universal method for naming and grouping organisms that underpins modern taxonomy. The other scientists are known for different contributions—Darwin for evolution by natural selection, Mendel for genetics, Pasteur for microbiology and germ theory—so they don’t fit the description.
