Difficulty: Medium
About this MCQ
This Medium Data Structures MCQ checks one syllabus fact.
The question is: “A tree data structure in which each node has at most two children. What is this concept called?”
The accepted answer is D. Binary tree. “A tree data structure in which each node has at most two children. What is this concept called” is answered by Binary tree (option D). Option A (“Trie”) does not match the stem; it is a near-miss used to catch incomplete recall of Binary tree. Option B (“Stack”) does not match the stem; it is a near-miss used to catch incomplete recall of Binary tree. Remaining alternatives (Queue) fall outside the same rule and should be eliminated once Binary 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.

Why not B: “Stack” is not correct. The accepted answer is D. Binary tree. “A tree data structure in which each node has at most two children. What is this concept called” is answered by Binary tree (option D). Option A (“Trie”) does not match the stem; i
- C. Queue
Why not C: “Queue” is not correct. The accepted answer is D. Binary tree. “A tree data structure in which each node has at most two children. What is this concept called” is answered by Binary tree (option D). Option A (“Trie”) does not match the stem; i
