Option C is correct because it uses pointer arithmetic to copy each character from `string2` to `string1` and then increments both pointers. This effectively replaces the functionality of lines 5 and 6 in the original code, which copies characters from `string2` to `string1` one by one in a loop until it reaches the null terminator (which is represented by the condition becoming false when the copied character is '\0').
