Answer

The correct answer is a. static double DetermineGrade(int grade1, int grade2, int grade3)

Explanation:

  • The method name "DetermineGrade" accepts three integer parameter grade values, grade1,grade2 and grade3.
  • This method should return the average with a fractional component. So, return type should be "double".
  • The values represent grades in this method. They should be unchangeable in the method. So, it should be "static".

So, the correct answer is (a).
