Polymorphism in C#

so here's a basic question on Polymorphism in C#, i found at SO. looking for the basics these days.

class A {
    public virtual void Method1(){}

    public void Method2() {
        Method1();
    }
}

class B:A {
    public override void Method1() { }
}

class main {
    A myobject = new B();
    myobject.Method2();
}

So which function gets called?

B.Method1();

gets called because it properly overrides the virtual method A.Method1();
