How can you compress a tar file with gzip upon creation?

To compress a tar file with gzip upon creation, the command that should be used is structured as follows: "tar -z -c". In this context, the option 'c' stands for "create," indicating that you are creating a new tar archive. The 'z' option tells the tar command to use gzip for compression. By combining these two options, the resulting command effectively creates a new tar archive while simultaneously compressing its contents with gzip, producing a file with a .tar.gz extension.

The other options reflect different functionalities that do not achieve the goal of compressing a tar file with gzip during creation. For example, using 'j' is associated with bzip2 compression rather than gzip, while 'x' means "extract," which is not applicable for creating a new file. Lastly, 'f' is used to specify the filename, but it does not imply compression by itself. Therefore, the combination of 'z' and 'c' in the correct choice is essential for achieving gzip compression while creating a tar file.
