Which of the four characteristics is associated with being able to respond positively to challenges?

The characteristic that is associated with being able to respond positively to challenges is fortitude. Fortitude refers to mental and emotional strength in facing adversity, fear, or difficulty. Individuals with fortitude demonstrate resilience and the ability to persevere through tough situations, making them more apt to approach challenges with a proactive and positive mindset.

This strength is essential when confronting obstacles, as it allows individuals to maintain focus and composure, ultimately leading to better problem-solving and decision-making outcomes. In contrast, while responsibility involves being accountable for one's actions, and demeanor relates to an individual's outward behavior and attitude, neither specifically captures the essence of resilience in the face of challenges. Personality encompasses a broader range of traits and does not singularly address the quality of responding positively to difficulties. Thus, fortitude is the most fitting characteristic in this context.
