What is eustress?

Eustress refers to a form of stress that is beneficial and contributes positively to an individual's experience. It is often considered "good stress" because it helps motivate individuals, encourages personal growth, and can enhance performance in various situations, such as during a job interview or while preparing for a competition. Eustress is generally perceived as manageable and is associated with feelings of excitement and fulfillment, making it an important factor in achieving goals and facing challenges.

The other options do not accurately capture the essence of eustress. For instance, stress that causes a negative response is typically classified as distress, which is detrimental to well-being. The concept of eustress does not involve the absence of any stress, as it acknowledges that certain levels of stress can be advantageous. Additionally, while it is true that some stress can be harmful, eustress specifically refers to situations where stress is constructive rather than harmful. Thus, the definition of eustress as "good stress that causes a positive response" is what makes this answer correct.
