The correct answer is Wealth Maximization. Financial management aims to maximize the wealth of the shareholders by making decisions that increase the value of the company's stock. This involves making strategic investment decisions, managing cash flow efficiently, and optimizing the capital structure. While sales maximization and profit maximization are important goals, they may not necessarily lead to long-term wealth creation. Similarly, assets maximization focuses on increasing the size of the company's assets, but it may not necessarily result in maximizing shareholder wealth. Therefore, wealth maximization is the most appropriate purpose of financial management.
