Show answer & explanation
Correct answer: A
The correct answer is Option A: Enqueue. An Enqueue operation inserts an element into the queue. When a circular queue is completely full, there are no vacant memory slots available. Attempting to insert another element triggers a Queue Overflow error, making the operation impossible.
