* Option B (Correct):Theuseraddcommand with-mcreates a home directory for the user, and the-s /bin
/bashoption assigns the Bash shell. However, no password is set when the user is created withuseraddunless explicitly done with thepasswdcommand afterward.
* Option A (Incorrect):There is no mention of adding the user to thewheelgroup; theuseraddcommand does not imply this.
* Option C (Incorrect):The command does not automatically set a password; it only creates the user account with the specified shell.
* Option D (Incorrect):The-moption ensures that a home directory is created.

Option C (Correct):If a device named/dev/hdbwith theide-diskdriver is discovered, a symbolic link/dev
/sparediskwill be created, pointing to/dev/hdb.
Option D (Correct):TheKERNEL=="hdb"match specifies that the device will have the kernel device name
/dev/hdb.
Option A (Incorrect):This is incorrect because existing symbolic links are not overwritten unless explicitly defined.
Option B (Incorrect):The device itself is not renamed to/dev/sparedisk; rather, a symbolic link is created.
Option E (Incorrect):The rule specifically requires bothKERNEL=="hdb"andDRIVER=="ide-disk"to match; it is not an either/or condition.
