The compareTo() method should return a negative value if the current object is less than the passed object, a positive value if it is greater, and 0 if they are equal. Integer.compare() method does this for us by returning a negative value if the first argument is less than the second, zero if they are equal, and a positive value if the first argument is greater than the second. Therefore, option D is the best choice as it directly uses the Integer.compare() method to compare the temperatures.
