Which of the following is a commonly used web browser?

Google Chrome is a widely used web browser recognized for its speed, simplicity, and versatility. It allows users to easily navigate the internet, access web-based applications, and utilize various extensions to enhance browsing functionality. Its integration with other Google services and regular updates to improve security and performance contribute to its popularity.

In contrast, other choices do not meet the criteria of a web browser. Internet Explorer, while historically significant, has largely been replaced by Edge in the more recent technological landscape. Windows Media Player is a media player used for playback, and File Explorer is a file management utility for navigating files and directories on a computer system. These distinctions clarify why Google Chrome stands out as the clear answer for a commonly used web browser.
