On (A={1,2,3,4}), (R={(1,3),(3,2),(2,4),(1,2),(3,4)}). Which pair is compulsory to add to make it transitive?

Answer and explanation

Correct answer: ((1,4))

Step 1: Since ((1,2)) and ((2,4)) are in the relation, ((1,4)) must be present. Step 2: ((1,3)) and ((3,4)) also require ((1,4)), but it is absent. Step 3: When one missing pair is required in more than one way, add that pair first.
