Question

Which operation in a queue removes an element?

• A. Push
• B. Pop
• C. Enqueue
• D. Dequeue

Hint:

To remember queue operations, think of a real-life queue (line). New people enqueue at the back, and people at the front are served and dequeue from the line.

Answer 1

The Correct Option is D

Let's define the standard operations for stacks and queues:
Stack Operations:
Push: Adds an element to the top of the stack. Pop: Removes an element from the top of the stack.
Queue Operations:
Enqueue: Adds an element to the rear (end) of the queue. Dequeue: Removes an element from the front (start) of the queue.
The question asks for the operation that removes an element from a queue.
Based on the standard terminology, this operation is called Dequeue.
