What is the effect of attempting to compile and run this Java program that consists of two class definitions in separate files: 
public class One
{
   public int getValue()
   {  return x;
   }

   public void setValue(int theX)
   {  x = theX;
   }

   protected int x = 3;
}

public class Two
   extends One
{
   public void setValue(int theX, int theY)
   {  x = theX + theY;
   }

   public static void main(String[] args)
   {  Two obj = new Two();
      obj.setValue(2);
      System.out.println(obj.getValue());
   }
}
(a) The program compiles and, when run, displays 2.
(b) It compiles and, when run, displays 3.
(c) It compiles and, when run, displays 5.
(d) It doesn't compile.
