The best option for Stacy to prepare her test results for a formal presentation would be to use the Report Wizard to create a report. This tool allows her to design a professional-looking report that organizes and presents the data effectively, making it suitable for a formal setting.
Other options, like printing the database in Table view or copying and pasting data into a word-processing document, may not provide the same level of formatting and clarity that a well-structured report can offer. Exporting the data to a text file may also not meet the needs for a formal presentation. Using the Report Wizard is the most appropriate and efficient choice in this context.
