Consider the following operation along with Enqueue and Dequeue operations on queues, where k is a global parameter. <syntaxhighlight lang="c"> MultiDequeue(Q){ m = k while (Q is not empty) and (m > 0) { Dequeue(Q) m = m – 1 } } </syntaxhighlight> What is the worst case time complexity of a sequence of $n$ queue operations on an initially empty queue?
(A) $Θ(n)$
(B) $Θ(n + k)$
(C) $Θ(nk)$
(D) $Θ(n^2)$
