Which term refers to a relation that assigns exactly one output value to each input from a given set?
Difficulty: Medium
About this MCQ
This Medium Discrete Mathematics MCQ checks one syllabus fact.
The question is: “Which term refers to a relation that assigns exactly one output value to each input from a given set?”
The accepted answer is B. Function (mapping). Function (mapping) is the person, body, or term that satisfies “Which term refers to a relation that assigns exactly one output value to each input from a given set” (option B). Option A (“Relation”) does not match the stem; it is a near-miss used to catch incomplete recall of Function (mapping). Option C (“Proposition”) does not match the stem; it is a near-miss used to catch incomplete recall of Function (mapping). Remaining alternatives (Boolean algebra) fall outside the same rule and should be eliminated once Function (mapping) is identified. Discrete Mathematics questions of this type reward precise definitions rather than approximate associations. Discrete Mathematics recall of this distinction is a regular item in FPSC, PPSC, NTS, and CSS papers.

Why not D: “Boolean algebra” is not correct. The accepted answer is B. Function (mapping). Function (mapping) is the person, body, or term that satisfies “Which term refers to a relation that assigns exactly one output value to each input from a given set” (option B). Op
Correct answer
B. Function (mapping)
Explanation
