Which of these correctly defines server-side scripting?

Server-side scripting refers to scripts that are executed on the web server before any content is sent to the client's browser. This process allows dynamic content generation, where the server processes requests, interacts with databases or other services, and generates the appropriate HTML or data to be sent back to the user's browser for rendering.

By running scripts on the server, developers can create personalized user experiences, handle form submissions, and perform operations that require secure access to resources, such as databases or file systems. The server-side environment ensures that sensitive operations and data management can be handled securely.

The other options highlight different functionalities and environments, which do not align with the fundamental concept of server-side scripting. Scripts that run in the user's browser are categorized as client-side scripting, whereas the suggestions regarding server load and database interaction don't accurately represent the essence of how and why server-side scripts are used.
