    Answer;

    B) All items in the freezer are at the same temperature as each other.

    Explanation; According to the Zeroth Law of Thermodynamics, if two systems are each in thermal equilibrium with a third system, then they are also in thermal equilibrium with each other. The zeroth law is important as it allows us to define the concept of a temperature scale. Zeroth Law results from thermal equilibrium and allows a conclusion that temperature is a physical quantity. In our case, a good example will be the fact that All items in the freezer are at the same temperature as each other, as they are sharing the temperature provided by the refrigerator.
