In a vehicle mileage application, you enter number of miles traveled by a vehicle and the amount of fuel used for 30 consecutive days. From this data the average monthly mileage of the vehicle is calculated. Which of the following should be done to improve the program design?
A) The next time the average monthly mileage is calculated, use copy and paste to avoid making coding errors.
B) Provide the same comment every time you repeat the average monthly mileage calculation.
C) Consider writing a method that returns the average monthly mileage as a double value.
D) Consider writing a method that returns void

Writing a method that returns the average monthly mileage as a double value would improve the program design as it would make the code more modular and reusable. It would also help in reducing errors and inconsistencies in the calculation of the average monthly mileage. Copy and paste can introduce errors, and repeating the same comment does not add any value to the program. Writing a method that returns void would be unnecessary as the program needs to return a value.
