The correct answer is A and B.
The CD (Change Directory) command is used to change the current working directory. The CHDIR (Change Directory) command is another name for the CD command. The MOVE command is used to move files from one directory to another. The MOVE DIR command is not a valid command.
To use the CD command, type CD followed by the name of the directory you want to change to. For example, to change to the Documents directory, you would type CD Documents.
To use the CHDIR command, type CHDIR followed by the name of the directory you want to change to. For example, to change to the Documents directory, you would type CHDIR Documents.
To use the MOVE command, type MOVE followed by the name of the file you want to move, followed by the name of the directory you want to move it to. For example, to move the file MyFile.txt to the Documents directory, you would type MOVE MyFile.txt Documents.
I hope this helps!
