Which of the following illustrates a financial behavior that lacks planning?

Impulsive purchasing on credit represents a financial behavior that lacks planning because it often involves making spur-of-the-moment decisions without considering the long-term financial implications. This behavior can lead to accumulating debt without a clear strategy or the ability to repay, which can destabilize an individual's financial situation.

In contrast, creating a budget is a structured approach to managing finances, enabling individuals to plan their income and expenditures wisely. Consolidating debts involves a deliberate strategy to manage and reduce overall debt burden, indicating thoughtful financial management. Diversifying investments reflects a proactive approach to risk management, ensuring that an individual’s investment portfolio is balanced and efficiently positioned for growth. These behaviors all signify a well-thought-out financial plan where decisions are made based on thorough consideration of financial goals and circumstances.
