Language/Type: C# arrays multi-dimensional arrays

Consider the following method:

public static void Mystery2d(int[][] a)
{
    for (int r = 0; r < a.Length; r++)
    {
        for (int c = 0; c < a[0].Length - 1; c++)
        {
            if (a[r][c + 1] > a[r][c])
            {
                a[r][c] = a[r][c + 1];
            }
        }
    }
}

If a two-dimensional array named numbers is initialized to store the following integers, what are its contents after the call shown?

int[][] numbers = {
    {3, 4, 5, 6},
    {4, 5, 6, 7},
    {5, 6, 7, 8}
};
Mystery2d(numbers);

`numbers[0][0]`
`numbers[0][1]`
`numbers[0][2]`
`numbers[0][3]`
`numbers[1][0]`
`numbers[1][1]`
`numbers[1][2]`
`numbers[1][3]`
`numbers[2][0]`
`numbers[2][1]`
`numbers[2][2]`
`numbers[2][3]`
