I think the correct answer is A. Since milk has a higher KE than the ice cubes, KE is being transferred from the milk to the molecules of ice which increases the kinetic energy of the molecules of ice. Consequently, it raises the temperature of the ice while lowering the temperature of the milk until they reach equilibrium at a final temperature.
