Which type of document serves as a record of official proceedings or events?

The correct choice, reports, serves as an official record of proceedings or events because they are structured documents that provide detailed information, analysis, and summaries of what has taken place in specific situations, meetings, or studies. Reports can include data, observations, conclusions, and recommendations, making them essential for documentation and future reference.

In professional settings, reports are often used to communicate important information comprehensively and formally, ensuring that there is a reliable account of what occurred during events or meetings. This makes them a critical tool for maintaining transparency and accountability.

In contrast, business letters are typically used for direct communication between parties, conveying specific messages rather than serving as a comprehensive record. Emails, while useful for communication, are often informal and may lack the structure necessary for capturing detailed proceedings. Templates are resources that provide a framework for creating various documents but do not themselves serve as records of events or proceedings.
