Which three code fragments, added individually at highlighted, produce the output 100? (choose 3)

class Inner{   
  private int x;   
  public void setX(int x) {    
    this.x=x;   
  }   
 public int getX(){   
   return x;   
 }   
}   
class Outer{   
  private Inner y;   
 public void setY(Inner y) {   
    this.y=y;   
  }   
 public Inner getY(){   
    return y;   
  }   
}    
public class Gamma{   
 public static void main(String [] args){   
  Outer o=new Outer();   
 Inner i=new Inner();   
  int n=10;   
 i.setX(n);   
  o.setY(i);   
 /* insert code here. */   
  System.out.println(o.getY().getX());   
 }   
}

n = 100;
i.setX( 100 );
o.getY().setX( 100 );
i = new Inner(); i.setX( 100 );
o.setY( i ); i = new Inner(); i.setX( 100 );
i = new Inner(); i.setX( 100 ); o.setY( i );
