C. Anaima and enaima
D. Arboreal and terrestrial

Answer 1

Hint: Aristotle divided the organisms into animals with blood and animals without blood. This means there were only two types of categories used which were simple and easy to classify.

Complete answer: Taxonomy is the study of classifying organisms according to their natural relationships. First-person to give taxonomy was the philosopher Aristotle, sometimes called the "father of science." It was Aristotle who first introduced the two key concepts of taxonomy that we practice today. He grouped the species according to their same properties like animals that have blood that lives on land and animals which do not have blood that lives on the water. This classification of animals showed similarity in animals that fall under the same groups. The idea was to organize animals in a hierarchy of their existence. He decided to show the classification from a lower to a higher order. He assumed that humans fall on the highest hierarchy and grouped accordingly. He interpreted the terms “ladder of nature” and “Great Chain of Being" which were not made by him but proved the statements.
He also designed the idea of naming with two names “binomial”. Aristotle's idea was to define or to place every object in a family and then to differentiate it from the other members of that family by some unique characteristic. He referred to humans as “rational animals”. He used the terms anaima for no red blood animals and enaima for red blood animals. In modern taxonomy, it can be called as enaima, vertebrates, and anima, invertebrates.
Hence, the correct option is C.

Note: Although Carl Linnaeus gave the modern taxonomy, Aristotle gave the most reliable taxonomy and his ideas were the same. Linnaeus used the idea of animal morphology and Aristotle used the idea of animals and their habits.
