Correct option is D
Given: Freezer : Chill
A freezer is an appliance that chills or cools items by lowering their temperature.
Now, we analyze options.

A fridge cools items but does not produce gas as its primary function.
Option (b): Steam : Boil (Incorrect)
A fridge cools items but does not produce gas as its primary function.
Option (c): Snow : Ice (Incorrect)
Steam is the result of boiling, but steam itself does not cause boiling.

A geyser heats water and releases steam, just like a freezer causes chilling.
Thus, correct option is (d).
