Which module management command is used to display help information?

The command that is used to display help information for module management is "modprobe --help." The modprobe command is a utility in Linux that is used to add and remove modules from the Linux kernel. When you append the --help option to this command, it provides users with a summary of how to use modprobe, including available options and their functionalities. This is particularly useful for users who may need guidance on the command's usage without delving into more complex documentation.

Other commands listed also relate to kernel module management, but they do not inherently provide help information in the same way. For example, modinfo is used to display information about a specific module, while rmmod is utilized for removing modules. Similarly, lsmod lists currently loaded modules. None of these commands include a built-in help option like --help that provides general usage information when invoked in this manner. Therefore, modprobe --help is clearly the correct choice for displaying help information regarding module management.
