Which of the following is an example of a CMS program?

The correct choice, which is Drupal, is a robust content management system (CMS) that enables users to create, manage, and modify digital content on websites without needing extensive technical knowledge or coding skills. Drupal provides a user-friendly interface, allowing for comprehensive handling of website content, from text and images to multimedia. Its modular architecture supports a wide range of functionalities and can be customized with various themes and plugins, making it a preferred choice for building complex and scalable websites.

In contrast, the other options listed serve different purposes. While Excel is primarily a spreadsheet application suitable for data analysis and organization, Photoshop is a powerful graphic design software focused on image editing and manipulation. PowerPoint, on the other hand, is a presentation software designed for creating slide-based presentations. None of these options offer the content management capabilities that a CMS like Drupal provides, which is specifically tailored for managing and organizing web content efficiently.
