I picked these options and always got the priorities for the public.
Spoilers...
Tell the public about the assassins. Don't tell the nobles or Kham.
Celebrate the coronation with everyone. I also did protection for both parade and ceremony.
Keep curtains drawn.
Pick first option about the keeper who doesn't come to coronation. Publicly condemning them.
I always get the option for Lady Naza. From what she says, she prefers a crown who is in charge and in my own words has a spine.
