Question

Quizplus · Accepted Answer

A circular list can be created from a singly linked list by making the last node (tail) point to the first node (head), which is achieved with the statement `tail.next = head;`. This creates a loop where traversing the list from head will eventually lead back to the head, hence forming a circle. Options B, C, and D involve syntax or properties not applicable to a singly linked list structure.
