In a circular singly linked list, what does the last node point to?
Correct answer D. The first node
Explanation
In a circular list the final node's next pointer wraps around to the first node instead of being null, so there is no natural end. This lets you traverse the whole list from any node and is convenient for round-robin scheduling. Traversal loops must therefore stop when they return to the starting node, not when they meet a null pointer.
