What might prolonged stress lead to in an individual?

Prolonged stress can have significant negative impacts on an individual's physical and mental health. Chronic stress activates the body's stress response systems, which can lead to a range of physical symptoms such as fatigue, headaches, digestive problems, and weakened immune function. Over time, this constant state of stress can contribute to serious health issues, including cardiovascular disease, obesity, and anxiety or depression.

Moreover, the toll of ongoing stress can lead to physical exhaustion, as the body becomes overworked and does not have adequate time to recover. This exhaustive state can impair a person's ability to think clearly and function optimally in daily activities. Therefore, the association between prolonged stress and physical exhaustion, along with a variety of potential health complications, makes this answer the most accurate reflection of the consequences of chronic stress.

The other options suggest benefits or positive outcomes associated with stress, which is generally not supported by research and understanding of stress effects on health.
