MS DOS is a disk operating system that was developed by Microsoft for IBM personal computers. It was first released in 1981, and it was the most popular operating system for personal computers in the 1980s and early 1990s. MS DOS is a command-line operating system, which means that users interact with it by typing commands at a prompt.<\/p>\n<p>B. OS\/2 is a computer operating system that was jointly developed by IBM and Microsoft. It was released in 1987, and it was intended to be a successor to MS DOS. OS\/2 was a multitasking, multiuser operating system that was designed to be more powerful and user-friendly than MS DOS. However, it was not as successful as Microsoft had hoped, and it was eventually discontinued in 2006.<\/p>\n<p>C.
