Which of the following is a financial statement?

An income statement is a financial statement that provides a summary of a company's revenues, expenses, and profits or losses over a specific period of time, typically a fiscal quarter or year. It is a key component of financial reporting and helps stakeholders assess the financial performance of the organization. The income statement outlines how much money was made (revenues) and how much was spent (expenses), ultimately indicating the company's profitability.

On the other hand, a service agreement is a contractual document that outlines the terms and conditions for services provided between parties, but does not reflect financial performance. A partnership contract similarly establishes the relationship and obligations between business partners but does not convey financial results. Operating procedures detail the processes and protocols a company follows in its operations, focusing on internal functionality rather than financial performance. Thus, the income statement stands out as the only option that directly delivers financial information, making it the correct answer.
