Who gave a famous natural classification system for plants?

Correct answer: Bentham and Hooker

Correct answer: B, George Bentham and Joseph Dalton Hooker. They produced a detailed and influential natural classification of seed plants, especially angiosperms, by considering a broad combination of morphological features rather than relying on only one superficial character. A is incorrect because Linnaeus is chiefly associated with binomial nomenclature and an artificial system based on selected characters. C is incorrect because Whittaker proposed a five-kingdom system for all major groups of organisms, not the famous natural plant classification asked here. D is incorrect because Carl Woese proposed the three-domain system using molecular evidence. The names in the options represent different parts of classification history. Memory cue: “Bentham–Hooker = natural classification of plants”; “Linnaeus = binomial names”; “Whittaker = five kingdoms”; “Woese = three domains.” This distinction helps avoid choosing a famous taxonomist merely because the question mentions classification.
