Difficulty: Hard
About this MCQ
This Hard Discrete Mathematics question asks: Bijective function is best defined as which of the following? The correct choice is B. A function that is both one-to-one and onto, pairing every element uniquely.. 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 set operation that combines all elements from two or more sets into a single set without duplication.
Why not A: “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 function that is both one-to-one and onto, pairing every element uniquely..
- B. A function that is both one-to-one and onto, pairing every element uniquely. ✓
- C. An operation that produces the set of all ordered pairs formed by combining elements from two sets.
Why not C: “An operation that produces the set of all ordered pairs formed by combining elements from two sets.” does not fit this question. The answer is A function that is both one-to-one and onto, pairing every element uniquely..
- D. A relation that is reflexive, symmetric, and transitive.
Why not D: “A relation that is reflexive, symmetric, and transitive.” does not fit this question. The answer is A function that is both one-to-one and onto, pairing every element uniquely..
Correct answer
B. A function that is both one-to-one and onto, pairing every element uniquely.
