In which year was Internet Explorer first released?

Option 3 : 1995

Internet Explorer  (formerly Microsoft Internet Explorer and Windows Internet Explorer,commonly abbreviated IE or MSIE) is a discontinued series of graphical web browsers developed by Microsoft and included as part of the Microsoft Windows line of operating systems, starting in 1995. It was first released as part of the add-on package Plus! for Windows 95 that year. Later versions were available as free downloads, or in service packs, and included in the original equipment manufacturer (OEM) service releases of Windows 95 and later versions of Windows.  On March 17, 2015, Microsoft announced that Microsoft Edge will replace Internet Explorer as the default browser on its Windows 10 devices. This effectively makes Internet Explorer 11 the last release. Internet Explorer will, however, remain on some versions of Windows 10 primarily for enterprise purposes. Starting January 12, 2016, only Internet Explorer 11 is supported with more security than older versions, according to Microsoft.  Support varies based on the operating system's technical capabilities and its support lifecycle.
