Why is it that when the temperature is at 0c, it says fog instead of
freezing fog?

Just because the temperature falls below the melting point of water it
does not mean that fog magically turns into freezing fog. Freezing fog
is *NOT* fog with a temperature below zero, despite what some say. For
fog to be freezing fog it has to be depositing rime. I have had this
argument before, as a professional observer many years ago in still air
we had a fog with a temperature just below zero, I was told off for not
calling it freezing fog, but I stood my ground as all surfaces were wet
despite the temperature, in no way was it rime icing.

So is freezing fog super cooled water droplets that turned into ice upon
contact of an object in the sub zero air?
