Hence, we have 5 choices for the first place which are 1, 2, 3, 7, 9. In the second and third place, we can place any given number. We have 6 choices for these places, which are 0, 1, 2, 3, 7, 9. So, the total numbers will be $5 \times 6 \times 6 = 180$ . Hence, option A will be the correct option.
