b) Mosaic

Mosaic, introduced in 1993, was the first widely used web browser and played a key role in popularizing the World Wide Web in the early 1990s. Developed at the National Center for Supercomputing Applications (NCSA), Mosaic offered a user-friendly interface and the ability to display text and images inline, significantly enhancing the web browsing experience. Mosaic’s introduction made the internet more accessible to the general public, fueling the growth of the web and the information age. It laid the groundwork for future web browsers and was instrumental in shaping the internet as we know it today.
