Which software is specifically used to display web pages?

Browser software is the correct choice because it is specifically designed to retrieve, present, and navigate web pages on the Internet. When you enter a URL in a browser, it connects to the web server, fetches the requested page, and displays it, allowing users to interact with the content. The functionality of a browser encompasses features such as bookmarks, history, tabs, and plugins, all geared toward enhancing the user experience while navigating the web.

Other options, while related to computing, serve different purposes. Network software generally refers to tools that manage network connections and data transfer rather than displaying web content. FTP software is used for transferring files between computers over the Internet and does not provide the functionalities necessary to display web pages. Mailer software is designed for sending and receiving emails, which has no direct connection to browsing the web. This clear distinction underscores why browser software is the essential tool for displaying web pages.
