Which command allows you to display the contents of a tar file?

The command that allows you to display the contents of a tar file is appropriately identified as the option that includes the flags for listing files without extracting them. Specifically, the flags used are 't' for listing the contents, 'v' for verbose output (which provides additional details, such as file sizes and permissions), and 'f' to specify that you are working with a file rather than standard input or output.

In this case, when you execute the command with the 'tvf' flags, you get a detailed view of all the files within the specified tar archive, making it easy to verify what is contained in the file without making any changes or extracting data.

The other options involve different actions: one is for creating a new tar file, another is for extracting files with verbose output, and the last is for appending files to an existing tar archive. Each of these commands serves its own distinct purpose but does not provide the capability to just display the contents of the archive.
