In the United States, utility patents expire after 20 years from the application date, while design patents expire after 14 years from the application date. Therefore, option A - 20, 14 - is the correct choice. Option B is incorrect because it lists the times in the wrong order. Option C is also incorrect because it lists both times as 20, which is not the case for design patents. Option D is not relevant to the question.
