The correct answer is C. Ethology.
Ethology is the scientific study of animal behavior. It is a subfield of zoology that focuses on the natural behavior of animals in their natural habitats. Ethology is concerned with the evolution, development, and function of behavior. It also studies the causes and consequences of behavior, and how behavior is influenced by the environment.
Euthenics is the science of improving human health and well-being through environmental factors such as nutrition, sanitation, and housing. Eugenics is the practice of improving human genetic traits through selective breeding. Ethnology is the study of human cultures.
Ethology is a valuable tool for understanding the natural world. It can help us to understand how animals interact with each other and with their environment. It can also help
us to understand the evolution of behavior. Ethology can be used to manage wildlife populations, to protect endangered species, and to study the effects of pollution on animal behavior.
