Please answer the question in C# and can be build through Visual Studio 2013...
The local driver's License Office has asked you to create a an application that grades the written portion of the driver's license exam. The exam has 20 multiple choice questions. Here are the correct answers: 1. B 2. D 3. A 4. A 5. C 6. A 7. B 8. A 9. C 10. D 11. B 12. C 13. D 14. A 15. D 16. C 17. C 18. B 19. D 20. A The program should store these correct answers in an array. The program should read the student's answers for each of the 20 questions from a text file and store the answers in another array. (Create your own text file to test the application) After the student's answers have been read from the file, the program should display a message indicating whether the student passed or failed the exam. (A student must correctly answer 15 of the 20 questions to pass the exam.) It should then display the total number of correctly answered questions, the total number of incorrectly answered questions, and a list showing the question numbers of the incorrectly answered questions.
