Its a silly question, however shocked to see different behaviors. Learning a lot.

Lets say I have two classes below

Class A
{
 public void Display()
 {
 }
}

Class B : A
{
 public void Display()
 {
 }
}

Class C : B
{
 public void Display()
 {
 }
}

Class Final
{
 static void Main()
 {
  var c = new C();
//  B c = new C();

//My doubt is, both of the above gives different results. May I know B c = new C() creates object of B or C? What I understood is, it creates object of B. Then why we say "new C()"? I agree with C c = new C(); But I thought, B b = new C(); creates object of B. Where we use this style? Only when utilizing runtime polymorphism? (Overriding methods)?
