Most likely C. One temperature control will be for one space - say one for storing frozen meat at -20oC %26amp; the other for chilled goods at say +4oC. The temperature controls simply shut the refrigerant flow to the space they control on or off. The system itself only runs when one or both of the control valves are open. When they are both shut the pressure on the low pressure side of the system falls %26amp; the compressor cuts out on low pressure.
