I am having a argument with my friend on psych questions whose right??? 10points?

It's D. If she were interested in (A) developmental psychology, the question would relate to changes and processes, typically those that occur over time. It it were (B) social psychology, the question would relate to our inter and intrsonal relationships and group dynamics. If she were interested in (C) behavioural psychology she would be interested in conditioning, such as rewards, punishments, etc. (D) Health psychology is the types of behaviours and motivations behind our lifestyle choices, particularly those that influence our health.
