This is a trick question. There is no such thing as a Freon® gauge, I called and asked Dupont®.
-
b, zero atmospheric pressure
Atleast on mine as mine will show a negative pressure (vacuum) when I have the vacuum pump going until I hit -32 bars.

B. 0 reading means no pressure whatsoever is on the system.

a and c assuming the your current atmospheric pressure is the average pressure at sea level and you are reading a pressure scale and not temperature
