For the string game = "Olympic2024", the objective is to locate the index of the character `"C"`. It is important to note that Python's string indexing is case-sensitive. The string `"Olympic2024"` includes a lowercase `"c"` at index 6, but it does not contain an uppercase `"C"`. The index() method requires an exact match and will generate a ValueError if the specified substring is absent. This differs from the find() method, which returns -1 upon failure to locate the substring, whereas index() raises an exception. As an uppercase `"C"` is not present in the string, Python will consequently raise a ValueError. Thus, the appropriate selection is option (D).
