Consider the following class definitions.public class BClass
{
Private int x; public void set(int a) { x = a; } public void print(){ }
}public class DClass extends BClass
{
Private int y; public void set(int a, int b)
{
//Postcondition: x = a; y = b;
}
Public void print(){ }
}Which of the following is the correct definition of the method set of the class DClass?(i)
Public void set(int a, int b)
{
Super.set(a);
Y = b;
}(ii) public void set(int a, int b)
{
X = a;
Y = b;
}
A) Only (i)
B) Only (ii)
C) Both (i) and (ii)
D) None of these

(i) is correct because it correctly uses `super.set(a)` to access the `set` method of the superclass `BClass` to set the value of `x`, and then sets `y` directly within `DClass`. (ii) is incorrect because it attempts to directly access `x`, which is private in the superclass and not directly accessible from `DClass`.
