Difficulty: Medium
About this MCQ
This Medium Data Structures question asks: Choose the correct description of Binary tree. The correct choice is D. A tree data structure in which each node has at most two children.. Read the options below, commit to one, then use the explanation to see why that choice holds and why the others do not.
Data Structures items like this one are written for Pakistan exams such as CSS, FPSC, PPSC, and NTS. The difficulty label is a hint about how much of the topic the stem assumes, not a score. Tags and exam names, when they are present, tell you where else the same idea is tested. Previous and next links stay in Data Structures so you can continue the subject. Related questions point at nearby stems if you want another angle on the same idea.
Treat the explanation as part of the question, not a footnote. If you missed it, reread the stem against the correct option before you open the next Data Structures item. A timed quiz is the same pool with a clock and a score. A past paper is a full sitting rather than this single question.
- A. A structure that stores elements in contiguous memory locations, allowing constant-time indexed access.
Why not A: “A structure that stores elements in contiguous memory locations, allowing constant-time indexed access.” does not fit this question. The answer is A tree data structure in which each node has at most two children..
- B. A linear data structure that follows the First-In-First-Out (FIFO) principle.
Why not B: “A linear data structure that follows the First-In-First-Out (FIFO) principle.” does not fit this question. The answer is A tree data structure in which each node has at most two children..
- C. A linear data structure that follows the Last-In-First-Out (LIFO) principle.
Why not C: “A linear data structure that follows the Last-In-First-Out (LIFO) principle.” does not fit this question. The answer is A tree data structure in which each node has at most two children..
- D. A tree data structure in which each node has at most two children. ✓
Correct answer
D. A tree data structure in which each node has at most two children.
Explanation
A tree data structure in which each node has at most two children. (option D) is the accepted answer to “Choose the correct description of Binary tree.”.
