In summary, the first and second laws of thermodynamics state that energy can't be or destroyed, it just changes forms. when energy changes forms, some energy becomes unusable energy. changed, kinetic created, heat created, potential changed, heat

Your answer is A changed, kinetic

created, heat

Explanation:

The summary above stated that the law of the thermodynamic ad states that the energy or heat a neither be created and hence it cannot be destroyed as it changes its forms or transforms into other matter and thus it also states the second law as energy moves to the other unstable forms of heat energy.  As heat is also referred to as the latent of the hidden energy and hence this energy changes and then transformed from one object to another object thus it doesn't get destroyed and is replaced by the same flow of mater or energy in the ecosystem. Thus the system continues to be in thermodynamic equilibrium.

Ithink the answer to that would be b):

The figure is not necessarily a parallelogram because only one diagonal is bisected and only one pair of sides is congruent.
