The method in.next() reads the next token from the input stream as a String. To read a single character from the text file, we can use the charAt(0) method to extract the first character of the string. Therefore, in.next().charAt(0) is the best option. The other options are incorrect as they either do not exist or do not serve the purpose of reading a single character from a text file.
