When creating a new sales division group, the command used is essential for properly establishing that group within the Linux system. The command to create a new group is executed using 'groupadd', followed by the desired name of the new group. In this case, 'groupadd eastern_sales_division' is the correct invocation to create a group specifically for the eastern sales division.

This command not only initiates the creation of the group but also ensures that it is registered in the system's group database, allowing users and permissions to be associated with it. As a result, any new group defined in this manner can effectively manage access and permissions related to the sales activities of that division.

The other options either attempt to modify an existing group or suggest actions that are logically sequenced after the group has been created, making them inappropriate as the first step in this process.
