Which is a web browser?

A web browser is essential software that allows users to access, retrieve, and view information and content on the World Wide Web. Google Chrome is the correct answer because it is a widely recognized and popular web browser developed by Google. It provides the interface and functionality for users to navigate websites, view multimedia, and interact with web applications seamlessly.

• Windows is incorrect; it is an operating system developed by Microsoft, which manages computer hardware and software resources, not a tool for browsing the internet.
• Linux is also incorrect; it is a family of open-source operating systems, similar to Windows, and not a web browser itself.
• MS Excel is incorrect; it is a spreadsheet program developed by Microsoft, used for data organization and calculations, making it an application software, not a web browser.
