About this MCQ
This Hard Discrete Mathematics question asks: Which of the following best names the concept in which a relation that is reflexive, antisymmetric, and transitive, used to describe orderings that are not necessarily total? The correct choice is B. Partial order relation. Read the options below, commit to one, then use the explanation to see why that choice holds and why the others do not.
Discrete Mathematics 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 Discrete Mathematics 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 Discrete Mathematics 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. Intersection (set operation)
Why not A: “Intersection (set operation)” does not fit this question. The answer is Partial order relation.
- B. Partial order relation ✓
- C. Degree of a vertex
Why not C: “Degree of a vertex” does not fit this question. The answer is Partial order relation.
- D. Power set
Why not D: “Power set” does not fit this question. The answer is Partial order relation.
Correct answer
B. Partial order relation
Explanation
Partial order relation is the term that matches “Which of the following best names the concept in which a relation that is reflexive, antisymmetric, and transitive, used to describe orderings that are not necessarily total” (option B). Option A (Intersection (set operation)) does not fit this question. Option C (Degree of a vertex) does not fit this question. Option D (Power set) does not fit this question. For this Discrete Mathematics question, the accepted answer is Partial order relation.
