(D) The correct option is $D$.When ice is crushed,the total surface area of the ice that comes into contact with the surrounding air or the contents of the cooler increases significantly.According to the principles of heat transfer,the rate of heat exchange is directly proportional to the surface area in contact.Therefore,increasing the surface area by crushing the ice accelerates the rate of heat absorption from the surroundings,thereby speeding up the cooling process.
