On (A={x,y,z}), which pair is needed to make (R={(x,x),(z,z),(x,y),(y,z)}) reflexive?

Answer and explanation

Correct answer: ( (y,y) )

Step 1: A reflexive relation needs self-pairs for (x,y,z). Step 2: ((x,x)) and ((z,z)) are present, but ((y,y)) is missing. Step 3: Add the self-pair of the missing element.
