Which of the following best describes a "spendthrift" personality?

The term "spendthrift" specifically describes a person who spends money extravagantly and often wastefully. Such individuals tend to have little regard for budgeting or saving, choosing instead to indulge in unnecessary expenditures. This behavior contrasts sharply with personalities characterized by frugality, carefulness, prudence, or meticulousness, which emphasize saving and thoughtful management of financial resources. Therefore, identifying a "spendthrift" personality as one that is extravagant and wasteful aligns perfectly with the definition of the word, making this choice the best description.
