    The correct answer is "Heat is just transformed, not created

    or destroyed".

    Explanation:

    The first law of thermodynamics describes what happens to heat added or absorbed by a system, in which it is indicated that the work plus the heat in a system is equal to the variation of the internal energy. Therefore the first law of thermodynamics describes how heat is transformed into work or stored in internal energy, not created or destroyed.
