This grid shows the state of a 2D array: The grid is created with this code: Which line of code, when inserted in place of //line n1, adds an X into the grid so that the grid contains three consecutive XS?
The correct answer is A. The answer D will return an exception because there is no way to access the 3rd place. Always remember that Java indexes from 0, to make a complete line of X we need to put an X in the second place from the third line and I say again, as java indexes from 0, so it is grid[2][1] = 'X';
The answer can't be D as 3 goes out of bounds of array, answer is A
