C# Oops constructor related question

What will be the output of below program

    class ConstructorConcept
    {
        static void Main()
        {
            ExtendedSample objExtendedSample = new ExtendedSample("Oops is very interesting");
            Console.ReadKey();
        }

        public class Sample
        {
         
            public Sample(string Val)
            {
                Console.WriteLine("I am in one argument constructor => Sample"); 
            }
        }

        public class  ExtendedSample:Sample
        {
            public ExtendedSample()
            {
                Console.WriteLine("I am in zero argument constructor => ExtendedSample"); 
            }

            public ExtendedSample(string Val)
            {
                Console.WriteLine("I am in one argument constructor => ExtendedSample"); 
            }
        }
    }

This program will not compile because in base class we don’t have zero argument constructor.
