Explanation:

Among the given options, 'dBase III' (often written as DBASE III or dBase 3) was a highly popular and widely used database management system for MS-DOS based personal computers during the 1980s. It was a foundational product for many business applications. 'Coral' is not a recognized database package in this context; it might be a misspelling or an obscure reference. 'WordStar' was a prominent word processing application, not a database. 'AutoCAD' is a computer-aided design (CAD) software, used for 2D and 3D design and drafting, completely unrelated to database management. Therefore, dBase III is the correct answer.
