Answer:B) O(n)

Explanation: Linked chain is the type of the chain that gets created through the linking of the objects.This is done by the link established between the  objects/elements with the consecutive attachment. In this chain, enqueue is the operation that functions for the insertion/addition of the elements in the queue.So, while enqueuing operation takes place in a chain, it requires the O(n) time.
