In order to read data from a file, we need to create a file object first using File class and then we need to create a Scanner object to read data from this file. Choice A creates a file object, but it does not create a Scanner object to read data from the file. Choice B tries to create a Scanner object directly from the file name, which is not possible. Choice D creates a PrintWriter object, which is used to write data to a file, not read from it. Therefore, choice C is the best choice as it creates both the file object and the Scanner object to read data from the file.
