What is the function or purpose of Partial order relation?
Difficulty: Hard
About this MCQ
This Hard Discrete Mathematics question asks: What is the function or purpose of Partial order relation? The correct choice is B. A relation that is reflexive, antisymmetric, and transitive, used to describe orderings that are not necessarily total.. 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. A symbol or word, such as AND, OR, or NOT, used to combine or modify propositions in logic.
Why not A: “A symbol or word, such as AND, OR, or NOT, used to combine or modify propositions in logic.” does not fit this question. The answer is A relation that is reflexive, antisymmetric, and transitive, used to describe orderings that are not necessarily total..
- B. A relation that is reflexive, antisymmetric, and transitive, used to describe orderings that are not necessarily total. ✓
- C. The number of edges connected to a given vertex in a graph.
Why not C: “The number of edges connected to a given vertex in a graph.” does not fit this question. The answer is A relation that is reflexive, antisymmetric, and transitive, used to describe orderings that are not necessarily total..
- D. A set operation that combines all elements from two or more sets into a single set without duplication.
Why not D: “A set operation that combines all elements from two or more sets into a single set without duplication.” does not fit this question. The answer is A relation that is reflexive, antisymmetric, and transitive, used to describe orderings that are not necessarily total..
Correct answer
B. A relation that is reflexive, antisymmetric, and transitive, used to describe orderings that are not necessarily total.
Explanation
A relation that is reflexive antisymmetric and transitive used to describe orderings that are not necessarily total is the value that answers What is the function or purpose of Partial order relation option B Option A A symbol or word such as AND OR or NOT used to combine or modify propositions in logic does not fit this question Option C The number of edges connected to a given vertex in a graph does not fit this question Option D A set operation that combines all elements from two or more sets into a single set without duplication does not fit this question For this Discrete Mathematics question the accepted.
