Consider the following method, which is intended to return the number of columns in the two$-$dimensional array arr for which the sum of the elements in the column is greater than the parameter val.

public int countCols$($int$[][]$ arr, int val$)$

$\{$

int count $=0$;

for $($int col $=0$; col $<$ arr$[0].$length; col$++)//$ Line $5$

$\{$

int sum $=0$;

for $($int$[]$ row : col$)//$ Line $8$

$\{$

sum $+=$ row$[$col$]$; $//$ Line $10$

$\}$

if $($sum $>$ val$)$

$\{$

count$++$;

$\}$

$\}$

return count;

$\}$

The countCols method does not work as intended. Which of the following changes should be made so the method works as intended?

Responses

Line

should be changed to for $($int col $=0$; col $<$ arr.length; col$++)$

Line $5$ should be changed to for $($int col $=0$; col $<$ arr.length; col$++)$

Line

should be changed to for $($int row : col$)$

Line $8$ should be changed to for $($int row : col$)$

Line

should be changed to for $($int$[]$ row : arr$)$

Line $8$ should be changed to for $($int$[]$ row : arr$)$

Line

should be changed to sum $+=$ arr$[$col$]$;

Line $10$ should be changed to sum $+=$ arr$[$col$]$;

Line

should be changed to sum $+=$ arr$[$row$][$col$]$;
