DHeat will flow from the air in the refrigerator

Verified Answer :

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

The correct answer is option A

The heat will not flow because there is no temperature difference between the substances. The cheese, the dish and the refrigerator are having the same temperature so there will be no heat flow. For the heat flow there must be temperature difference between the substances and here there is no temperature difference so there will be no heat flow.
