Q6. Given the code fragment: 

int [][] array2d = new int[2][3]; 

System.out.println("Loading the data."); 

for ( int x = 0; x < array2d.length; x++) { 

for ( int y = 0; y < array2d[0].length; y++) { 

System.out.println(" x = " + x); 

System.out.println(" y = " + y); 

// insert load statement here. 

System.out.println("Modify the data. "); 

for ( int x = 0; x < array2d.length; x++) { 

for ( int y = 0; y < array2d[0].length; y++) { 

System.out.println(" x = " + x); 

System.out.println(" y = " + y); 

// insert modify statement here. 

Which pair of load and modify statement should be inserted in the code? The load 

statement should set the array's x row and y column value to the sum of x and y 

The modify statement should modify the array's x row and y column value by multiplying it by 2 

A. Load statement: array2d(x,y) = x + y; 

Modify statement: array2d(x,y) = array2d(x,y) * 2 

B. Load statement: array2d[x y] = x + y; 

Modify statement: array2d[x y] = array2d[x y] * 2 

C. Load statement: array2d[x,y] = x + y; 

Modify statement: array2d[x,y] = array2d[x,y] * 2

D. Load statement: array2d[x][y] = x + y; 

Modify statement: array2d[x][y] = array2d[x][y] * 2 

E. Load statement: array2d[[x][y]] = x + y; 

Modify statement: array2d[[x][y]] = array2d[[x][y]] * 2
