The missing code should create a PrintWriter object to write to the output file. The correct constructor for PrintWriter takes a String parameter that represents the name of the output file. Therefore, choice A is the best option. Choice B creates a Scanner object, which is used for input, not output. Choice C creates a PrintWriter object but with an undefined variable outputFile. Similarly, choice D creates a Scanner object for an undefined output file.
