Final answer:
A. keep, remove
Escape behaviors remove a person from a stressful situation after the exposure, whereas avoidance behaviors keep a person from such situations entirely.
Step-by-step explanation:
The terms escape behaviors and avoidance behaviors relate to how individuals respond to stress or threat. Escape behaviors remove a person from a situation they find aversive, after they have already been exposed to it. Conversely, avoidance behaviors keep a person from entering a situation that they perceive as potentially threatening or uncomfortable, thereby preventing the encounter altogether. These behaviors are implemented as coping strategies, and understanding them is crucial within the context of the psychological coping mechanisms in stress management and anxiety disorders.
