The brief, written message typically used for internal communication within an organization is called a "Memo."

Here is the step-by-step reasoning:

1. Proposal: A proposal is a detailed plan or suggestion put forward for consideration or discussion by others. It is usually more formal and detailed than a brief message and is often used for external communication or to suggest new projects or initiatives.

2. Memo: A memo (short for memorandum) is a brief, written message used for internal communication within an organization. It is typically used to inform employees about policies, procedures, or other important information.

3. Report: A report is a detailed document that presents information in an organized format for a specific audience and purpose. Reports are usually longer and more detailed than memos and can be used for both internal and external communication.

4. Financial Statement: A financial statement is a formal record of the financial activities and position of a business, person, or other entity. It is a detailed document that includes information such as income, expenses, assets, and liabilities. Financial statements are not typically used for brief internal communication.

Therefore, the correct answer is Memo.
