Which of the following code performs a multiplication by $5$ of the elements of the array defined as:

int$[][]$ vals $=$ new int$[50][100]$;

Presume that the array has been properly initialized and filled with values.

for$($int $i=0$; $i$ vals.length; $i++)\{$

vals $[i][0.\mathrm{.}99{]}^{**}=5$;

$\}$

for$($int $i=0$; $i$ vals.length; $i++)\{$

for$($int $j=0$;$j$ vals$[$i$].$length; $j++\{$

vals $[i][j]**=5$;

$\}$

$\}$

for$($int $i=0$;$i$ vals.length; $i++)\{$

for$($int $j=0$;$j$ vals.length; $j++)\{$

vals $[i][j]**=5$;

$\}$

$\}$

for$($int $i=0$;$i$ vals.length; $i++$

for$($int $j=0$;$j$ vals$[$i$].$length; $j++)\{$

vals$[$j$][$j$]*=5$;

$\}$

$\}$

for$($int $i=0$;$i$ vals.length; $i++)\{$

vals $[i{]}^{**}=5$;

$\}$
