Ammonia:- 107.9.
Carbon Dioxide:- 70.
Sulpher Dioxide:- 104.
R-12:- 252.
These are the freezing points of the four refrigerants in deg. celsius, so we can say that carbon dioxide has highest freezing point.

High freezing point means it freezes at a higher temperature. Meaning 0 degrees is a higher freezing point than -27 degrees.

Ammonia = -77.
Carbon dioxide = -78.5.
Sulphur dioxide=-72.
R12= - 157.7.
Carbon dioxide = -78.5.
Sulphur dioxide=-72.
R12= - 157.7.

The freezing point of ammonia, co2, so2 & R12 are -77.73c, -78.5c, -72c and -157.7c respectively. So the correct answer id sulphur dioxide.

Co2 freezing point is -56.6.
And the boiling point is -78.5.
It's opposite characteristics than others.
