Given the declarations below representing 5x4 2D arrays, select all of the statements that will set the 3rd row, 4th element of the arrays to 5.

1. numbers 1 [2] [3] = 5;
2. numbers 2 [2 * 4 + 3] = 5;
3. numbers 3 [2] [3] = 5;
4. numbers 1 [2 x 4 + 3] = 5;
5. numbers 2 [2][3] = 5;
6. numbers 3 [2 * 4 + 3] = 5;

int numbers1[5] [4]; int * numbers2 = malloc (5*4*sizeof(int)); int ** numbers3 = malloc (5 * sizeof(int *)); for (int r = 0; r < 5; r++) { numbers3[r] malloc(4 *sizeof(int)); }
