Which of the following best describes the work of a web developer?

The work of a web developer is primarily focused on creating and maintaining websites. This encompasses a range of tasks including writing code, designing user interfaces, and ensuring that websites are functional, responsive, and user-friendly. Web developers work with various technologies and programming languages, such as HTML, CSS, JavaScript, and sometimes backend technologies to develop interactive and dynamic websites.

Creating a website involves not only developing the visual elements that users interact with but also implementing the functionality that makes those elements work. Maintenance of a website includes updating content, fixing bugs, and ensuring that the site remains compatible with new technologies and devices.

While embedding security protocols, data collection and analysis, as well as system design and architecture are important aspects of IT, they typically fall under other specific roles or disciplines within the technology sector rather than defining the core responsibilities of a web developer. Thus, option B accurately reflects the primary focus and responsibilities of a web developer.
