Consider a grid of $\backslash (\backslash$mathrm$\{$m$\}\backslash$times $\backslash$mathrm$\{$n$\}\backslash )$ cells, where m is the number of rows and n is the number of columns. The grid is represented by a list of lists called grid. Which cell of the grid does the following code segment print?

$```$

O

$1$ for row$\_$index in range$(0,$ m$)$:

for col$\_$index in range$(0,$ n$)$:

if row$\_$index $==$ m$-1$ and col$\_$index $==$ n$-1$:

print$($grid$[$row$\_$index$][$col$\_$index$])$
