Which of the following commands would you use to extract files from a tar archive?

The command to extract files from a tar archive is represented by using the -x option with the tar command. This option specifically stands for "extract," instructing the tar utility to extract files from an existing tar archive file. When using this command, you would typically also specify the name of the tar file from which you want to extract data, ensuring the action is performed correctly.

In the context of tar command options, -f is used to indicate the filename of the archive but does not perform any extraction by itself. The -c option is for creating a new tar archive, which means it packages files rather than extracting them. The -t option lists the contents of the tar archive without extracting any files, allowing users to see what is inside the archive. Thus, the option specifically designed for extracting files is the -x option.
