The subtraction needs to be performed digit by digit starting from the rightmost digit. 6 - 5 = 1, 9 - 9 = 0 (with a borrow of 1), 5 - 8 = -3 (with a borrow of 1), 1 - 2 = -1 (with a borrow of 1), 7 - 8 = -1 (with a borrow of 1), B - 2 = 9 (with a borrow of 1), B - 8 = 3 (with a borrow of 1), 1 - T = -5 (with a borrow of 1), e - B = 3, 1 - 8 = -7. Thus, the result is 14,811. Therefore, the best choice is C. - Start with the rightmost digits, 6-1 = 5
- Carry over 1, then 7-5 = 2
- D-8 cannot be performed, so borrow 1 from the next digit over
- 16-8 = 8, and we can then perform the remaining subtraction: 10-2=8
- So the final answer is 14,811.
