@Divyank.

Then it should be So2.

I agree @Baby and @Divyank.

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

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

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.
