What is printed by the following $\text{ANSI C}$ program?

#include<stdio.h>

int main (int argc, char *argv[])

{

        int a[3][3][3] =

        {{1, 2, 3, 4, 5, 6, 7, 8, 9}, 
         {10, 11, 12, 13, 14, 15, 16, 17, 18},
         {19, 20, 21, 22, 23, 24, 25, 26, 27}};

    int i = 0, j = 0, k = 0;

    for ( i = 0; i < 3; i ++) {

        for ( k = 0; k < 3; k++)

            printf(“%d”, a[i][j][k]);

        printf (“\n”);

    }

    return 0;

Answer: A

The 3D array a[3][3][3] consists of $3$ two-dimensional arrays, each of size $3 \times 3$ . The initialization assigns values row-by-row to these sub-arrays:

For $i = 0$ : a[0] is initialized with values $1$ to $9$ . $a[0][0] = \{1, 2, 3\}, \quad a[0][1] = \{4, 5, 6\}, \quad a[0][2] = \{7, 8, 9\}$
For $i = 1$ : a[1] is initialized with values $10$ to $18$ . $a[1][0] = \{10, 11, 12\}, \quad a[1][1] = \{13, 14, 15\}, \quad a[1][2] = \{16, 17, 18\}$
For $i = 2$ : a[2] is initialized with values $19$ to $27$ . $a[2][0] = \{19, 20, 21\}, \quad a[2][1] = \{22, 23, 24\}, \quad a[2][2] = \{25, 26, 27\}$

In the nested loop, the variable j remains constant at $0$ . The loop prints a[i][0][k] for $i \in \{0, 1, 2\}$ and $k \in \{0, 1, 2\}$ :

When $i = 0$ : Prints a[0][0][0], a[0][0][1], a[0][0][2] $\implies$ 1 2 3
When $i = 1$ : Prints a[1][0][0], a[1][0][1], a[1][0][2] $\implies$ 10 11 12
When $i = 2$ : Prints a[2][0][0], a[2][0][1], a[2][0][2] $\implies$ 19 20 21

Thus, the correct option is A.
