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};
intMyArr is a reference to a 2-D jagged array.
The two rows of the jagged array intMyArr are stored in adjacent memory locations.
intMyArr[0] refers to the zeroth 1-D array and intMyArr[1] refers to the first 1-D array.
intMyArr refers to intMyArr[0] and intMyArr[1].
