Which of the following is the study of biological bases of social behavior? A. Ethnobiology B. Pavlov's response C. Sociobiology D. Nature-nurture controversy

The answer is c i believe sociobiology

In this question you see the words "social" and "biology" of which you could simply guess the correct answer as Sociobiology, but ...

The correct answer would be Sociobiology because sociobiology is the scientific study of the biological (especially ecological and evolutionary) aspects of social behavior in animals and humans.

Ethnobiology is the scientific study of the way living things are treated or used by different human cultures. It studies the dynamic relationships between people, biota, and environments, from the distant past to the immediate present. Therefore, it is not the best fit as an answer.

Pavlov's response is based all around a conditioned response, which is an automatic response established by training to an ordinarily neutral stimulus. Therefore, this doesn't fit either because it is based on one specific general study.

Nature-nurture controversy is a traditional and long-standing disagreement over whether heredity or environment is more important in the development of living things, especially human beings, so, this is not the correct answer either as it is based of an idea rather than even a study.
