E)none of the above

Quizplus · Accepted Answer

The only difference between the two given correspondences is in the fourth group of characters. In the first correspondence it is "4fc3" and in the second correspondence it is "76d4". This indicates that in the composite function, some operation needs to be performed on the fourth group to get from "4fc3" to "76d4".

Converting "4fc3" and "76d4" to binary form and comparing the bits, we can see that only the third bit from the left is different. This suggests that the operation performed is a bit flip.

Performing a bit flip on "4fc3" we get "9de6", which matches with the second option. Therefore, the correct answer is B.
