B Correct answer
Explanation

When hot liquid mixes with cold liquid, heat flows from the higher temperature region to the lower temperature region until thermal equilibrium is reached. This mixing process increases the overall entropy of the system because the energy becomes more dispersed and the system moves toward a more disordered state.
