Answer 1

The correct Answer is D. MS-DOS and UNIX

Step-by-step explanation:

The Character User Interface (CUI) operating system is referred to as command-based. It is a text-based operating system, were text is used for interacting with the software or files by typing commands to perform specific tasks. The command line operating system uses only keyboard to enter commands. The command line operating systems include DOS and UNIX. The advanced command line operating system is faster then the advanced GUI operating system.

Answer 2

D.MS-DOS and UNIX

Step-by-step explanation:

The oldest versions of Windows Operating Systems used MS-DOS. MS-DOS was purely command-line based OS. MS-DOS did not have GUI and users were required to learn command lines to help them navigate through, open, and manipulate files. MS-DOS is no longer used. UNIX was also a command-line based operating system when it was initially built in the 1960s. It still is but it supports both GUI and CLI. Unix, in my opinion, is hands down the best and most powerful CLI based OS to have ever been built.
