What best describes a report in Microsoft Access?

A report in Microsoft Access is best described as a formatted document designed for the structured presentation of database data. It serves to compile, summarize, and present the data in a coherent and organized way, allowing users to generate printed output or visually display their data in a professionally formatted manner.

Reports allow for the use of various formatting options, such as headers, footers, grouping, and sorting, which enhances readability and communicates information effectively. They can be customized based on the requirements of the user, making it possible to highlight specific data points or trends that are important for analysis or reporting purposes.

In contrast, other options describe functions or characteristics that do not define a report. For example, a plain text document does not provide the structured and formatted presentation that reports are known for. External storage merely refers to data archiving and is not related to presentation. Lastly, a plugin that enhances navigation does not pertain to the purpose or design of a report within Access, which is focused primarily on data presentation.
