Solution

The correct option is A Ice at 00C
Ice is more effective than water in cooling liquids because ice needs additional energy to convert itself to water at zero degree celsius. Thus it absorbs more heat from the liquid system making the liquid system cooler so ice at 00C is cooler than water at 00C.
