Answer:
Charakan
Step-by-step explanation:
The odd one out would be Charakan.
Theophrastus, Carl Linnaeus, and Aristotle are all scientists that contributed to the science of classification of living organisms (taxonomy).
Aristotle was the first scientist to classify living organisms into plant and animal kingdoms based on the artificial system of classification.
Theophrastus was a student of Aristotle and he wrote a book, De Historia Plantarum, classifying about 480 plants.
Carl Linnaeus invented the binomial system of naming living organisms in which organisms are given two names - the species and the genus name.
Charakan has no known contribution to taxonomy. Hence, the name is the only odd one.
