Final answer:
Data stored as an Adobe PDF file cannot be imported into a table in Microsoft Access, as PDFs are not structured for database manipulation.
Step-by-step explanation:
The question is asking which type of file cannot be imported into a table in Microsoft Access. The correct answer is Adobe PDF. This is because Adobe PDF files are typically used for documents that are meant to be viewed and printed, not manipulated as raw data.
When dealing with database management systems like Access, users usually import data from formats that are structured for data manipulation, such as Excel spreadsheets, Access database files, or text files (like those created with Notepad), where fields are typically delineated in a way that Access can recognize.
