• A. Cognitive Psychology
• B. Neuropsychology
• C. Health Behavior
• D. Health Psychology

Answer: (D)

Health psychology investigates how psychological factors influence physical health. It looks at how thoughts, emotions, stress, social context, and health-related behaviors shape health outcomes, illness risk, coping with disease, and interactions with the healthcare system. This field also explores interventions to promote wellness, adherence to treatment, and quality of life. The other options focus on different areas: cognitive psychology studies mental processes like memory and problem-solving; neuropsychology examines how brain function relates to behavior; health behavior centers on specific actions people take to maintain or improve health. Health psychology uniquely ties together these psychological processes with physical health, making it the best fit for the question.
