How to create JaggedArray in C#

A Jagged Array is an Array of Array

   string[][] Arr = new string[3][];
            
            Arr[0] = new string[3];
            Arr[1] = new string[2];
            Arr[2] = new string[1];

            Arr[0][0] = "Bachelor";
            Arr[0][1] = "Masters";
            Arr[0][2] = "PHD";

            Arr[1][0] = "Bachelor 1";
            Arr[1][1] = "Masters  1";

            foreach (string[] b in Arr)
            {
                foreach (string a in b)
                {
                    Console.WriteLine(a);
                }
            }

            Console.ReadKey();


            // we can also create a JaggedArray of type object 

            object[][] arr2 = new object[3][];

            arr2[0] = new object[3];
            arr2[0][0] = 1;
            arr2[0][1] = "String";
            arr2[0][2] = Arr;
