About this MCQ
This Easy Data Structures question asks: Which of the following best describes Queue? The correct choice is B. A linear data structure that follows the First-In-First-Out (FIFO) principle.. 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 linear data structure that follows the First-In-First-Out (FIFO) principle..
- B. A linear data structure that follows the First-In-First-Out (FIFO) principle. ✓
- C. A binary tree in which each node's left subtree contains smaller values and right subtree contains larger values.
Why not C: “A binary tree in which each node's left subtree contains smaller values and right subtree contains larger values.” does not fit this question. The answer is A linear data structure that follows the First-In-First-Out (FIFO) principle..
- D. A data structure where elements are stored in nodes, each pointing to the next node in sequence.
Why not D: “A data structure where elements are stored in nodes, each pointing to the next node in sequence.” does not fit this question. The answer is A linear data structure that follows the First-In-First-Out (FIFO) principle..
Correct answer
B. A linear data structure that follows the First-In-First-Out (FIFO) principle.
