If (R) is reflexive and (A={4,5,6}), which statement is always true?

Answer and explanation

Correct answer: ((4,4),(5,5),(6,6)\in R)

Step 1: If a relation is reflexive, every element is related to itself. Step 2: For (4,5,6), the pairs ((4,4),(5,5),(6,6)) must be present. Step 3: Reflexivity alone does not decide other pairs.
