How will you complete the foreach loop in the C#.NET code snippet given below such that it correctly prints all elements of the array a?

    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(); 
    }
