What does the "fight or flight" response prepare the body for?

The "fight or flight" response is a physiological reaction that occurs in response to a perceived threat, preparing the body to either confront the danger (fight) or escape from it (flight). This response is triggered by the release of stress hormones, such as adrenaline and cortisol, which lead to several changes in the body. These changes include increased heart rate, heightened alertness, and the release of energy reserves, all designed to maximize the individual's chances of survival in a dangerous situation.

Given the options, the focus of the "fight or flight" response is specifically on dealing with threats rather than on relaxation, social interaction, or basic needs such as eating and sleeping. Therefore, the correct answer emphasizes this critical survival mechanism that prepares individuals for immediate action in face of potential harm or danger.
