Answer: Option (B) is the correct answer.
Explanation:
According to the law of mass of conservation, energy can neither be created nor it can be destroyed as it can only be transferred from one place to another.
Thus, in a closed system the matter cannot be exchanged as the system is closed but there can be transfer of energy from the system to the surrounding.
Thus, we can conclude that energy will be exchanged, but matter will not be exchanged.
