This demonstrates the profit and expenses for a given month and includes year-to-date information for a given year.

The income statement is the correct choice because it specifically outlines a company's revenues and expenses for a particular period, typically a month, while also providing a year-to-date summary. This financial document allows stakeholders to understand the profit or loss generated over that timeframe, making it an essential tool for assessing financial performance. In contrast, a balance sheet provides a snapshot of a company's assets, liabilities, and equity at a specific point in time, and a cost-benefit analysis evaluates the overall value of a project by comparing its costs to the expected benefits. The term "net worth" generally refers to an individual's or an entity's total assets minus total liabilities, not specifically presenting detailed financial operations like an income statement does.
