What is the purpose of using Bootstrap in Dreamweaver?

The purpose of using Bootstrap in Dreamweaver is to create responsive and mobile-first web pages quickly. Bootstrap is a front-end framework that provides a collection of CSS and JavaScript components designed to help developers build responsive layouts easily. It utilizes a grid system that automatically adjusts to various screen sizes, allowing developers to create websites that function well on both desktop and mobile devices without extensive custom coding.

By incorporating Bootstrap within Dreamweaver, designers can take advantage of its ready-to-use styles and components, such as navigation bars, buttons, forms, and modals, thereby speeding up the web development process. This framework also ensures adherence to best practices in responsive design, which is essential in today's digital landscape where users access websites on a wide range of devices.

Using Bootstrap does not primarily serve the creation of static web pages, enhance image editing capabilities, or develop desktop applications, as those functionalities fall outside its intended use. Thus, the emphasis on responsive and efficient web design makes option C the best choice.
