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 produces a set containing only the elements common to two or more sets.
Why not A: “A set operation that produces a set containing only the elements common to two or more sets.” does not fit this question. The answer is A logical statement that is always true regardless of the truth values of its individual components..
- B. A function that is both one-to-one and onto, pairing every element uniquely.
