D . uname -m

Answer: C

Explanation:

The command that will display the operating system is uname -o. This command uses the uname tool, which is used to print system information such as the kernel name, version, release, machine, and processor. The -o option stands for operating system, and prints the name of the operating system implementation (usually GNU/Linux).

The other options are not correct commands for displaying the operating system. The uname -n command will display the network node hostname of the system. The uname -s command will display the kernel name of the system. The uname -m command will display the machine hardware name of the system.
