Sigmund Freud:

A. is considered the father of behaviorism.
B. stressed the importance of the unconscious.
C. considered crime as essentially an environmental failure.
D. developed reality therapy as a mode of rehabilitation.

I think it's B

I believe you are correct.

"His analysis of dreams as wish-fulfillments provided him with models for the clinical analysis of symptom formation and the mechanisms of repression as well as for elaboration of his theory of the unconscious as an agency disruptive of conscious states of mind." ~Wiki-pedia

The above Wiki-pedia quote is what made me think B as the answer, therefore thinking you are correct.

I hope this helps! :)

B is correct.

You are correct, Sigmund Freud stressed the importance of the unconscious. To arrive at this answer, you can eliminate options A, C, and D because they are not associated with Freud. To further verify your answer, you can consult reliable sources such as textbooks, academic papers, or reputable websites that provide information about Sigmund Freud's work and contributions. These sources will confirm that Freud is indeed renowned for his emphasis on the role of the unconscious mind in shaping human behavior and mental processes.
