A.

Heat will not flow because there is no temperature difference between the substances.

B.

The temperature of the air in the refrigerator will decrease and the temperature of the cheese will increase.

C.

The temperature of the cheese will increase and the temperature of the dish will decrease.

D.

Heat will flow from the air in the refrigerator

I haven't studied heat transfer yet, but I'm fairly certain that it's A).

Since the ambient temperature is set to 3.0C, and we're already told that both objects that are touching are at 3.0C, then no change is made because thermal equilibrium has already been met. I think this refers to the Zeroth Law of Thermodynamics.

I would see if anyone else could confirm this
