A Correct answer
Explanation

An input-restricted deque allows deletions from both ends but restricts insertions to only one end. This is a specialized deque variant - unlike standard deques (full operations at both ends) or output-restricted deques (opposite restriction). Priority queues use different ordering principles entirely.
