In a typical nested for loop used to process a two$-$dimensional array, following the end of each execution of the inner for loop:

$($Note: to be clear, "execution of the inner for loop" means that all iterations of the inner for loop have been completed, i$.$e$.,$ the condition of the inner for loop has failed, thus inner for loop has been fully executed.$)$

Group of answer choices

The outer for loop increments its counter variable

The inner for loop increments its counter variable

The inner for loop initializes its counter variable

The outer for loop initializes its counter variable
