Since we are subtracting two hexadecimal numbers, we need to borrow from the leftmost digit if the digit on the right is smaller. 
Starting from the rightmost digit, we have:
8 - 7 = 1
E - 6 = 8
4 - D = -9, so we borrow 1 from the next digit and have 14 - D = 7
0 - B = -11, so we borrow 1 from the next digit and have 10 - B = 5
1 - A = -9, so we borrow 1 from the next digit and have 11 - A = 1
1 - 9 = 8
2 - 2 = 0
1 - 1 = 0
Therefore, the result is 882. When converted to decimal, it is 2,226.
When subtracting from TBX8967_00 (which is not given in hexadecimal), we can simply subtract the decimal equivalents.
TBX8967_00 is equal to:
(11 x 16^6) + (13 x 16^4) + (8 x 16^3) + (9 x 16) + 7 = 295,361,032
Subtracting the decimal equivalent of 882 from this gives:
295,361,032 - 882 = 295,360,150
Converting back to hexadecimal gives  B as the answer choice.
