The question is asking for the sum of hexadecimal numbers. To add hexadecimal numbers, each place value (16^0, 16^1, 16^2, etc.) should be added separately. Starting from the rightmost digits:

1 + 5 = 6 (no carry) 
9 + 2 = B (no carry)
A + F = 19 (carry of 1 to the next place value)
1 + 7 + 1 = 9 (carry of 1 to the next place value)
B + 0 + 0 = B (no carry) 
7 + 3 + E = 18 (carry of 1 to the next place value)
1 + B + F + F = 2B (carry of 1 to the next place value)
1 + C + E = 2B (no carry)

Therefore, the sum is 11eb651f_cbb1_0739_b0a1_911f870ee18a. Choice C matches this result.
