As we can see, the only difference between the two given codes is in the third segment - the fourth character has changed from 4 to 5. Each segment comprises four characters, each of which can take 16 possible values (0-9 and a-f), making the total number of possibilities in each segment to be 16^4 = 65,536. Therefore, the difference between the two codes can be found by subtracting the numerical value of 9029_e from that of 9029_f, which is 15. This difference is then reflected in the last segment of the code, which changes from 6b200bb75087 to 8fafb7b6152a. The rest of the digits in the code remain the same. Therefore, the answer is C) 27.
