Either....

They meant "runtime polymorphism" (late binding) (so as to know if you know the difference between compile-time and runtime polymorphism).

Or...

The question was fired to confuse you.

There are concepts like:

I've never heard about virtual polymorphism. In most modern programming languages, these concepts are strongly related. IMHO, it's very academic to distinguish them (I mean: inheritance, virtual inheritance, polymorphism, subtype polymorphism).

There is nothing called virtual polymorphism.

You can achieve polymorphism by using virtual methods in C#.

That means if you declare a method virtual in base class you can override that method in child/derived classes to change it's behavior.

class Base
    {
        public virtual void SayHello()
        {
            Console.WriteLine("Hello from base");
        }
    }

    class Derived : Base
    {
        public override void SayHello()
        {
            Console.WriteLine("Hello from derived");
        }
    }
