Which of the following best describes a financial statement representing the cash inflow and outflow?

The Cash Flow Statement is specifically designed to detail the cash inflows and outflows of a business over a certain period. It provides a clear picture of how cash is generated and spent, categorizing activities into operating, investing, and financing sections. By focusing solely on the movement of cash, it helps stakeholders understand the company's liquidity and overall financial health.

In contrast, the Balance Sheet presents a snapshot of a company's financial position at a specific point in time, showcasing assets, liabilities, and equity but does not directly address cash flow. The Income Statement outlines revenues and expenses, indicating profitability but not the actual flow of cash. Lastly, the Statement of Shareholder Equity details changes in equity accounts over time but lacks the cash flow focus of the Cash Flow Statement. Thus, the Cash Flow Statement is the most appropriate choice regarding cash inflows and outflows.
