The correct response is: The water is still warmer than the ice cube, so thermal energy moves from the water to the ice cube.
This is because thermal energy always flows from a warmer object to a cooler one until thermal equilibrium is reached. In this case, even in a cold glass of water, if the water is warmer than the ice, heat will transfer from the water to the ice, causing the ice cube to melt.
