A program has a String variable fullName that stores a first name, followed by a space, followed by a last name. There are no spaces in either the first or last names. Here are some examples of fullName values: "Anthony Coppola", "Jimmy Carroll", and "Tom DeWire". Consider this code segment that extracts the last name from a fullName variable, and stores it in last Name with no surro no surrounding blanks: int k = fullName.indexOf(" "); //find index of blank String lastName = /* expression */ Which is a correct replacement for /* expression */? II fullName.substring (k+ 1); III fullName.substring(k + 1, fullName.length());
