The statement that is true about sources of stress is:
They vary based on age and location.
Sources of stress can change depending on a person's age, life circumstances, and cultural context, meaning that what might be a significant source of stress for one person may not be the same for another. The other statements are generally not accurate; stress sources can change over time, they can have a significant impact on health, and while therapy can help manage and reduce stress, it often does not eliminate all sources of stress entirely.
