ap csa java question

```public class Overload { public int average(int x, int y) { /* implementation not shown */ } public int average(int value1, int value2) { /* implementation not shown */ } // There may be instance variables, constructors, // and methods that are not shown. } II. public class Overload { public int average(int x, int y) { /* implementation not shown */ } public int average(int x, int y, int z) { /* implementation not shown */ } // There may be instance variables, constructors // and methods that are not shown. } III. public class Overload { public int average(int x, int y) { /* implementation not shown */ } public int average(double x, double y) { /* implementation not shown */ } // There may be instance variables, constructors, // and methods that are not shown. }``` Which of the attempts at method overloading will compile without error? A I only B II only C III only D II and III only E I, II, and III The answer is `D` I dont understand why 3 will compile since the paramters in the average method are different data types
