Consider the following operations on a Queue data structure that stores int values. $($enqueue puts item in a queue, whereas dequeue removes items$)$

Queue $q=$ new q$.$enqueue$(3)$; q$.$enqueue$(5)$; q$.$enqueue$(9)$;

System.out.println$($q$.$dequeue$())$;

q$.$enqueue$(2)$;

q$.$enqueue$(4)$;

System.out.printin$($q$.$dequeue$())$;

System$\_$out.println$($q$.$dequeue$())$;

q$.$enqueue$(1)$;

q$-$enqueue$(8)$;

After the code above executes, how many elements would remain in $q?$

$0$

$4$

$5$

$6$

$4.$ Woving to the neert question prevents changes to this answer.
