I found this question elsewhere on this site. I will repeat their answer to you, so all of the credit for answering this goes to Pandamille.
"C. Limit your fat and sugar intake and eat more fruit and vegetables."
Answer: behaviorism, psychodynamic, humanistic, cognitivism
And also its not cognition it is cognitivism.
The answer would be A, regulating the content of processed foods. There are so many processed foods in today's society that it is extremely difficult to avoid them.
Hope this helps
