About this MCQ
This Hard Discrete Mathematics MCQ checks one syllabus fact.
The question is: “Choose the correct description of Equivalence relation.”
The accepted answer is A. A relation that is reflexive, symmetric, and transitive.. Choose the correct description of Equivalence relation is answered by A relation that is reflexive symmetric and transitive option A Option B The number of edges connected to a given vertex in a graph does not match the stem it is a near-miss used to catch incomplete recall of A relation that is reflexive symmetric and transitive Option C A logical statement formed by negating and reversing both the hypothesis and conclusion of a conditional statement does not match the stem it is a near-miss used to catch incomplete recall of A relation that is reflexive symmetric and transitive Remaining alternatives A set operation that combines all elements from two or more sets into a single set without duplication fall.
