Explanation:

1. For "psychology" row:

Psychology is the study of mind and behavior. "Study" relates as it's what psychology does, "mind" and "behavior" are what it studies. "Declare" has no relation to psychology's focus.

A psychologist is a professional who does studies and provides treatment. "Decline" has no connection to a psychologist's role or work.

Claustrophobia is fear of enclosed spaces. "Scared" (emotion), "closed" (space type), "cramped" (space type) relate. "Agoraphobia" is fear of open spaces, a different phobia, not related to claustrophobia's definition context here.
