Inheritance: How the object is created?

[sivakumartn]

I am new to oops concepts. When I create an instance of derived class, of type base class then, how the object is created, like

class A
{
    public void methodA(){}
}
 
class B : A
{
    public void methodB(){}
}
 
When I create a instance like this
 
A obj = new B()

then how the object is created?, Is it A or B?, please answer me or give me any reference links.

Thanks in advance.
