This is a hexadecimal equation, so the possible values for each digit are 0-9 and A-F. To simplify the problem, we can convert the hexadecimal values to binary.
11eb69da_9ea6_f1de_af94_bd247a23a9a9_TB8311_11 = 
000100011101101101100110111010010011101111010100110111110001110101001000111010010000111010010111000100001001111000101101011110010000011010101001001001110101011001_TB8311_11
Next, we can see that the 4th digit from the right of the first number is 6, which in binary is 0110. The 4th digit from the right of the second number is 7, which in binary is 0111. Since we are subtracting, we need to borrow from the next digit to get 0110-1=0101. Therefore, the answer is:
11eb69da_9ea7_f1de_af94_bd247a23a9a9_TB8311_11, which corresponds to choice B.
