What term describes the following? a tree-based structure that satisfies the heap property, often used to implement priority queues.
Difficulty: Hard
About this MCQ
This Hard Data Structures MCQ checks one syllabus fact.
The question is: “What term describes the following? a tree-based structure that satisfies the heap property, often used to implement priority queues.”
The accepted answer is C. Heap. Heap is the fact required by “What term describes the following? a tree-based structure that satisfies the heap property, often used to implement priority queues.” (option C). Option A (“Binary tree”) does not match the stem; it is a near-miss used to catch incomplete recall of Heap. Option B (“Queue”) does not match the stem; it is a near-miss used to catch incomplete recall of Heap. Remaining alternatives (Binary search tree) fall outside the same rule and should be eliminated once Heap is identified. Data Structures questions of this type reward precise definitions rather than approximate associations. Data Structures recall of this distinction is a regular item in FPSC, PPSC, NTS, and CSS papers.
