Which of the following directories contains administrative commands and daemon processes in the Linux operating system?

/etc contains system-wide configuration files and shell scripts used to boot and initialize system settings, not executable administrative commands.

/dev contains device files that represent hardware and virtual devices such as disks, terminals, and random number generators, not commands or daemons.

/usr contains user-space applications, libraries, and documentation installed for general use, rather than core system administration binaries.

The /sbin directory (system binaries) holds administrative commands such as fsck, ifconfig, and init, as well as daemon processes required for system boot and administration, distinguishing it from /bin which holds binaries for all users.
