They say rm command defaults to the option --preserve-root. Is that right?
Otherwise I should put the line
alias rm='rm --preserve-root'`in ~/.bashrc to make that option happen without typing it every time I run the rm command. To confirm this I ran type rm, and got rm is hashed (/bin/rm).
I expected rm is aliased to rm --preserve-root. Does anyone know what's going on with the rm command?

rm is not being aliased to rm --preserve-root, but the option is selected by default in the rm binary.
From the manpage of rm in Ubuntu 17.10, you can find the following details of the --preserve-root and --no-preserve-root options:
--no-preserve-root do not treat '/' specially --preserve-root do not remove '/' (default)
