Q$1.$ Suppose that the following XML file exists in project directory:

Which of the following codes is correct to find the speed of fastest car and display it when the "FindFastestCar" button is clicked?

private void FindeFastestCar$\_$Click$($object sender$,$ EventArgs e$)$

I

XElement cars $=$ XElement.Load$(".../../../$cars$.$xml$")$;

int Max$=0$;

foreach $($var node in cars.Elements$("$car$").$ Elements$("$carMaxSpeed$"))$

if $($node$.$ Value $>$ Max$)$ Max $=$ node.Value$)$;

MessageBox.Show$("$The speed of fastest car is $"+$ Max$)$;

$\}$

private void FindeFastestCar$\_$Click$($object sender$,$ EventArgs e$)$

i

XElement cars $=$ XElement. cars.$($:$xm{l}^{\text{'}\text{'}}\}$;

int Max $=0$;

foreach $($var node in cars.Elements$("$car$").$ Elements$("$carMaxSpeed$"))$

if $($node $>$ Max$)$ Max $=$ node$)$;

MessageBox.Show$("$The speed of fastest car is $"+$ Max$)$;

$\}$

$\{$
