Which term describes the school of psychology that studies the reasons for behavior and how organisms adapt to environments?
vitfil [10]

Answer:

C

Explanation:

I was not quite sure what if my answer was correct, so using the process of elimination, I determined that it was.

Although Psychoanalysis seems like the correct answer since it looks close to the word Psychology, it is not the right because this term means a therapy to help mental illnesses, so that would not be the correct answer.

I continued to use the same process and I came to the conclusion that C is the correct answer.

Structuralism is when you try to understand the aspects of human cognition, behavior, culture, etc.

Hope this helps.
