recommended way disable recommends using apt

["jindam, vani" <jindam.vani@disroot.org>]

hello debian users,

i want to install again debian, i dont
want to install recommended packages 
and i checked (ex: $ apt show libreoffice) 
my list of packages to be installed & 
i see no problem. i always use $ sudo apt to 
install packages.

my plan:
(1) install debian base
(2) disable recommend packages
(3) install packages one by one

issue (which one is correct?) on /etc/apt/apt.conf:
(1) APT::Install-Recommends "false";
APT::Install-Suggests "false"; 
(2) APT::Install-Suggests "0";
APT::Install-Recommends "0";

regards,
jindam, vani
