What defines temerity?

Temerity is defined as excessive confidence or boldness, often in a rash or reckless manner. This term reflects a sense of audacity, where an individual acts despite potential risks or consequences, showing little regard for caution or safety. The correct choice captures this essence perfectly by linking it to both rashness and boldness, two qualities that characterize temerity. The other options describe different attributes that do not align with the meaning of temerity. For example, calmness and peace of mind contrast directly with the impulsive nature of temerity, while sharp sensation does not relate to character traits at all. Lastly, carelessness in duty implies negligence rather than the audacious bravado that temerity embodies.
