The command used to create directories in Linux is `mkdir`. This command stands for "make directory" and is followed by the name of the directory you want to create. When executing `mkdir <directory_name>`, the system will create a new directory with the specified name in the current working directory, provided you have the necessary permissions to create directories in that location.

Using `mkdir` is a fundamental operation in Linux for organizing files and creating structured directory layouts. This command can also accept options like `-p`, which allows the creation of parent directories as needed.

Other options provided are not valid commands to create directories in Linux. The command `create` is not recognized as a standard command in Linux. `touch` is designed primarily for creating empty files or updating the timestamps of existing files, not for creating directories. The term `newdir` does not correspond to any known command for directory creation. Thus, `mkdir` is the accurate and widely used command for this purpose in the Linux environment.
