Consider the following code segment:

int$[][]$ arr $=\{\{1,1,2,3,5,8\},$

$\{2,3,5,7,11,13\}\}$;

int sum $=0$;

for$($int r $=0$; r $<$ arr.length; r$++)\{$

for$($int c $=0$; c $<$ arr.length; c$++)\{$

sum $+=$ arr$[$r$][$c$]$;

$\}\}$

What is the value of sum at the end of the code?

$($A$)0($B$)1($C$)7($D$)12($E$)61$
