Stress reactions typically appear in four different categories. Which of the following is NOT one of these four categories?

• A. Emotional
• B. Physical
• C. Psychological
• D. Behavioral

Answer: (C)

Stress reactions are typically grouped into four domains: emotional, physical, cognitive, and behavioral. The option that isn’t part of that set is psychological, because it’s a broad umbrella term for mental processes rather than a distinct category in this framework. Cognitive covers thinking patterns like trouble concentrating or intrusive thoughts, while emotional covers mood and feelings, physical covers bodily symptoms, and behavioral covers observable actions. So psychological isn’t listed as its own category, making it the choice that doesn’t fit the four-domain pattern.
