What is printed by the following 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(" "); } return 0; }

The array a is a 3-dimensional array of shape $3 \times 3 \times 3$, initialized as follows:

1. First 2D block (a[0]):

   • a[0][0] = $\{1, 2, 3\}$

   • a[0][1] = $\{4, 5, 6\}$

   • a[0][2] = $\{7, 8, 9\}$

2. Second 2D block (a[1]):

   • a[1][0] = $\{10, 11, 12\}$

   • a[1][1] = $\{13, 14, 15\}$

   • a[1][2] = $\{16, 17, 18\}$

3. Third 2D block (a[2]):

   • a[2][0] = $\{19, 20, 21\}$

   • a[2][1] = $\{22, 23, 24\}$

   • a[2][2] = $\{25, 26, 27\}$

In the nested loop, $j$ remains fixed at $0$ throughout:

• When $i = 0$, $k$ ranges from $0$ to $2$, printing a[0][0][0], a[0][0][1], a[0][0][2], which gives: 1 2 3

• When $i = 1$, $k$ ranges from $0$ to $2$, printing a[1][0][0], a[1][0][1], a[1][0][2], which gives: 10 11 12

• When $i = 2$, $k$ ranges from $0$ to $2$, printing a[2][0][0], a[2][0][1], a[2][0][2], which gives: 19 20 21

Thus, the printed output matches (A).
