The best choice is C, because we need to pass a File object to the Scanner constructor, not just a string that represents the file name. Option A would also work if we change the argument to inputFile instead of inputFileName. Option B is incorrect because it is trying to create a Scanner object from the output file, not the input file. Option D creates a Scanner object to read from standard input, which is not what this code is intended to do.
