What would be the expected output after executing the following code?

function changeBase$($x$,$ base$)\{$

$$ const parsed $=$ parseInt$($x$,$ base$)$;

$$ console.log$("$Before parsed: $",$parsed$)$

$$ if $($isNaN$($parsed$))\{$ return $0$; $\}$

$$return parsed $*100$;

$\}$

$$ console.log$($changeBase$("1010",16))$

A$.$

$411200$

B$.$

NaN

C$.$

$1000$

D$.$

$10$
