Quizplus · Accepted Answer

To solve this, we need to find the difference between the two given strings and change the 4th character accordingly. 
In the first string, the 4th character is "c" and in the second string, it is "5". The difference between the ASCII values of "c" and "5" is 21. So, we need to add 21 to the 4th character of the first string to get the 4th character of the second string. 
Therefore, the 4th character of the second string will be "f". 
Hence, the answer is B, which has "f" as the 4th character.
