B. Energy transfer would occur between the copper bars and the surroundings.
Explanation:
In an isolated system, there is no energy transfer with surroundings but in an open system, energy transfer would occur between the copper bars and the surroundings.
An open system is a system in which energy exchange occurs with the surroundings.
In an isolated system, energy exchange does not occur with the surroundings.
We expect that in an open system, energy transfer would occur between the copper bars and also with the surrounding.
