Which of the following is a database application?

The correct answer is Access because it is specifically designed as a database management system that allows users to create, manage, and analyze relational databases. Access provides functionalities such as building tables for organizing data, running queries to retrieve specific information, and designing forms and reports for presenting that data effectively. This makes it a robust tool for handling complex data interactions and maintaining structured information.

In contrast, Excel is primarily a spreadsheet program used for calculations, data analysis, and visualization but it does not function as a full-fledged database. Word is a word processing application used for creating and editing text documents, while PowerPoint is used for creating presentations. These applications serve different purposes and lack the specialized database capabilities that Access offers.
