(c) Cimpletd

Reason: In the above code snippet, we have passed a string with value "Complete" and set character "i" and "d" at the index position 1 and 7, respectively. According to the string "Complete," "o" is at position 1, and "e" is at the position 7. The setChar() method is used to replace the original string values with the new one. Hence, the "o" and "e" are replaced by the characters "i" and "d," respectively, which results in "Cimpletd."
