About this MCQ
This Easy Discrete Mathematics question asks: Select the correct name for: the number of edges connected to a given vertex in a graph. The correct choice is D. Degree of a vertex. 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.
