Kasim,
Good evening. Below is the solution for Q2.
using System;
using System.Text.Json;

using static System.Console;

namespace ApplicationCore.Entities
{


    public class Person
    {
        public Guid Id { get; }

        public string Name { get; set; }

        public DateTime DateOfBirth { get; set; }

        public string City { get; set; }

        public Person()
        {
            Id = Guid.NewGuid();
        }

        public void Introduce(Person person) => WriteLine($"Hi {person.Name}, I am {Name}");

        public override string ToString() => JsonSerializer.Serialize(this);

        public static Person Parse(string personInformation) => JsonSerializer.Deserialize(personInformation);
    }

}
Write this code inside Main() method.
// Person Class
var person1 = new Person()
{
    Name = "Shiva Sai",
    DateOfBirth = DateTime.Now.AddYears(-25),
    City = "Hyderabad"
};
WriteLine($"Person 1: {person1}");

var clonedPerson1 = Person.Parse(person1.ToString());
WriteLine($"Cloned Person 1: {clonedPerson1}");
