The best choice for defining the Comparator interface for comparing Auto objects is option D because it uses the correct signature for the compare method in the Comparator interface, which takes two objects of the parameterized type and returns an integer value. The integer returned should be negative if the first object is smaller than the second, zero if they are equal, and positive if the first object is larger than the second.
