Which statement about Web site development is true?

The statement that web pages can be created using client-side and server-side scripting is accurate because modern web development frequently incorporates both types of scripting to create dynamic, interactive applications. Client-side scripting, which typically utilizes languages like JavaScript, enables immediate interaction with users in the browser without needing to communicate back to the server. This enhances the user experience by allowing real-time updates, animations, and form validation, making the webpage more responsive.

On the other hand, server-side scripting, often executed with languages such as PHP, Python, or Ruby, allows for complex operations like database interactions, user authentication, and generating dynamic content based on user requests. This server-side processing is crucial for creating websites that require customized responses, such as user-specific data or content fetched from a database.

Combining both client-side and server-side scripting allows developers to build more versatile and engaging web applications that can respond to user input while leveraging the power of the server for data processing and storage. This dual approach is a fundamental principle in contemporary web development, making it the correct answer.
