Identify the correct concept described as: a self-balancing binary search tree where the height difference between subtrees is at most one.
Difficulty: Hard
About this MCQ
This Hard Data Structures MCQ checks one syllabus fact.
The question is: “Identify the correct concept described as: a self-balancing binary search tree where the height difference between subtrees is at most one.”
The accepted answer is C. AVL tree. “Identify the correct concept described as: a self-balancing binary search tree where the height difference between subtrees is at most one.” is answered by AVL tree (option C). Option A (“Queue”) does not match the stem; it is a near-miss used to catch incomplete recall of AVL tree. Option B (“Binary search tree”) does not match the stem; it is a near-miss used to catch incomplete recall of AVL tree. Remaining alternatives (Stack) fall outside the same rule and should be eliminated once AVL tree 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.
