assume that a two-dimensional (2d) array arr of string objects with 3 rows and 4 columns has been properly declared and initialized. which of the following can be used to print the elements in the four corner elements of arr ? responses system.out.print(arr[0, 0] arr[0, 3] arr[2, 0] arr[2, 3]); system.out.print(arr[0, 0] arr[0, 3] arr[2, 0] arr[2, 3]); system.out.print(arr[1, 1] arr[1, 4] arr[3, 1] arr[3, 4]); system.out.print(arr[1, 1] arr[1, 4] arr[3, 1] arr[3, 4]); system.out.print(arr[0][0] arr[0][2] arr[3][0] arr[3][2]); system.out.print(arr[0][0] arr[0][2] arr[3][0] arr[3][2]); system.out.print(arr[0][0] arr[0][3] arr[2][0] arr[2][3]); system.out.print(arr[0][0] arr[0][3] arr[2][0] arr[2][3]); system.out.print(arr[1][1] arr[1][4] arr[3][1] arr[3][4]);
