What is wrong with the following code snippet that checks if a person is tall enough to ride the rollercoaster?

int height $=48$;

if$($height $<54)$

$\{$

boolean safe $=$ false;

$\}$

System.out.println$("$Is it safe to ride this rollercoaster? $"+$safe$)$;

Nothing wrong

A variable name has a typo in it$.$

A variable is accessed outside of its scope.
