The first statement correctly relates the 1st and 2nd laws of thermodynamics.
Explanation:
The first law of thermodynamics states that energy is conserved in whatever form it is, and so energy is neither created nor destroyed.
It establishes the relation between the various forms of energy in a system.
The second law of thermodynamics talks entropy and how work is done when energy is exchanged.
In all heat exchanges, heat is transferred from the warm body to the cooler one.
So the statement that correctly relates both these laws is Thermal-energy flow between objects is conserved and always flows from the warmer object to the cooler object.
