Which command is responsible for loading a module and its dependencies?

The command that is responsible for loading a module and its dependencies is "modprobe." This command is widely used in Linux systems to add or remove kernel modules, which are pieces of code that can be loaded into the kernel to extend its capabilities without the need for a system reboot.

When using "modprobe," the command automatically resolves and loads any dependencies that the specified module may have. This means that if a module relies on other modules to function, "modprobe" ensures that those dependent modules are also loaded first. This functionality is essential for maintaining the integrity and performance of the system, as it reduces the chances of module conflicts and ensures that all required functionalities are available.

Other options listed do not fulfill the same purpose. For example, "modprobe install" and "modprobe remove" do not exist as valid commands in this context, as "modprobe" itself inherently handles installation or removal of modules based on the context of use. "modprobe alias" refers to managing module aliases but does not pertain to loading modules and their dependencies. Thus, the choice of "modprobe" as the correct answer reflects its comprehensive role in managing kernel modules effectively while ensuring their functionality is preserved through dependency handling.
