The IndexOf and LastIndexOf methods are used to search for a substring within a string object and return the position of the first or last occurrence of the substring as an int value. Therefore, option A is the best choice. Option B (Insert and Remove) modifies the string object in some way and does not return an int value. Option C (ToUpper and ToLower) converts the string object to all uppercase or lowercase and does not search for a substring or return an int value. Option D (Substring and Trim) extract a substring or remove whitespace from the beginning and end of the string object and does not return an int value indicating the position of the substring.
