Answer 1

may be this will help:

abstract parent class:

 public abstract class Animal
    {

        private string name;

        public Animal(string name)
        {

            this.Name = name;
        }

        public Animal() { }
        public string Name
        {

            get { return this.name; }

            set { this.name = value; }

        }

        public virtual void talk()
        {

            Console.WriteLine("Hi,I am  an animal");

        }


    }

class with protected constructor:

public class Lion : Animal
    {
        private string yahoo;

        protected Lion(string name) : base(name)
        {

            this.Yahoo = "Yahoo!!!";
        }

        public string Yahoo
        {
            get
            {
                return yahoo;
            }

            set
            {
                yahoo = value;
            }
        }

        public Lion() { }
    }

class Kiara derived from Lion class :

 public class Kiara : Lion
    {

        public Kiara(string name) : base(name)
        {

        }

        public override void talk()
        {

            Console.WriteLine("HRRRR I'm a Kiara");

        }

        public Kiara() { }

    }

class Simba derived from Lion class :

    public class Simba : Lion
    {

        public Simba(string name) : base(name)
        {

        }

        public override void talk()
        {

            Console.WriteLine("HRRRR I'm a {0}  and this is my daughter:{1} {2}", 
            new Simba("Simba").Name, 
            new Kiara("Kiara").Name, 
            new Simba("Simba").Yahoo);
        }


        public Simba() { }

    }

implementation in main function:

       public static void Main(string[] args)
        {


            Animal lion = new Simba();
            lion.Name = "Simba";
            lion.talk(); 
            Animal lion1 = new Kiara();
            lion1.Name = "Kiara";
            lion1.talk();
        }
