Which of the following statements are correct about the C#.NET code snippet given below?

   int[][]intMyArr = new int[2][]; 
   intMyArr[0] = new int[4]{6, 1, 4, 3}; 
   intMyArr[1] = new int[3]{9, 2, 7};

    int[ , , ] a = new int[ 3, 2, 3 ]; 
    Console.WriteLine(a.Length);

1. int[] a = {25, 30, 40, 5};

2. int[] a;
   a = new int[3];
   a[0] = 25;
   a[1] = 30;
   a[2] = 40;
   a[3] = 5;

3. int[] a;
   a = new int{25, 30, 40, 5};

4. int[] a;
   a = new int[4]{25, 30, 40, 5};

5. int[] a;
   a = new int[4];
   a[0] = 25;
   a[1] = 30;
   a[2] = 40;
   a[3] = 5;

1. int[ , ] a;
   a = new int[2, 3]{{7, 1, 3},{2, 9, 6}};

2. int[ , ] a;
   a = new int[2, 3]{};

3. int[ , ] a = {{7, 1, 3}, {2, 9,6 }};

4. int[ , ] a;
   a = new int[1, 2];

5. int[ , ] a;
   a = new int[1, 2]{{7, 1, 3}, {2, 9, 6}};

    int[][]a = new int[2][];
    a[0] = new int[4]{6, 1 ,4, 3};
    a[1] = new int[3]{9, 2, 7}; 
    foreach (int[ ] i in a)
    {
        /* Add loop here */
        Console.Write(j + " ");
        Console.WriteLine(); 
    }

   int[][][] intMyArr = new int[2][][];

    int[] intMyArr = {11, 3, 5, 9, 4}; 

int[] a = new int[5]; 
int[] a = new int[10];

int[] a = int[5]; 
int[] a = int[10];

int[] a = new int[5]; 
a.Length = 10 ;

int[] a = new int[5]; 
a = new int[10];

int[] a = new int[5]; 
a.GetUpperBound(10);

    int[] a = {11, 3, 5, 9, 4}; 

1. The array elements are created on the stack.
2. Refernce a is created on the stack.
3. The array elements are created on the heap.
4. On declaring the array a new array class is created which is derived from System.Array Class.
5. Whether the array elements are stored in the stack or heap depends upon the size of the array.

    int[][] a = new int[2][];
    a[0] = new int[4]{6, 1, 4, 3};
    a[1] = new int[3]{9, 2, 7}; 
    Console.WriteLine(a[1].GetUpperBound(0));
