Polymorphism and c#

Question

Here one more basic question asked in MS interview recently

class A {
    public virtual void Method1(){}

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

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

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

So which function gets called? Sorry for the typos.

Answer 1

B.Method1();

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