Which of the following statements are correct about the C#.NET code snippet given below?
int[ , ] intMyArr = {{7, 1, 3}, {2, 9, 6}};- intMyArr represents rectangular array of 2 rows and 3 columns.
- intMyArr.GetUpperBound(1) will yield 2.
- intMyArr.Length will yield 24.
- intMyArr represents 1-D array of 5 integers.
- intMyArr.GetUpperBound(0) will yield 2.

Which of the following statements are correct about the C#.NET code snippet given below?
int[] a = {11, 3, 5, 9, 4};- The array elements are created on the stack.
- Refernce a is created on the stack.
- The array elements are created on the heap.
- On declaring the array a new array class is created which is derived from System.Array Class.
- Whether the array elements are stored in the stack or heap depends upon the size of the array.

Which of the following statements are correct about arrays used in C#.NET?
- Arrays can be rectangular or jagged.
- Rectangular arrays have similar rows stored in adjacent memory locations.
- Jagged arrays do not have an access to the methods of System.Array Class.
- Rectangular arrays do not have an access to the methods of System.Array Class.
- Jagged arrays have dissimilar rows stored in non-adjacent memory locations.
