Let (A={a,b,c,d}) and (R={(a,a),(c,c),(a,b),(d,c)}). (R) is not reflexive because which self-pairs are missing?

Answer and explanation

Correct answer: ((b,b),(d,d))

Step 1: A reflexive relation needs self-pairs for (a,b,c,d). Step 2: ((a,a)) and ((c,c)) are present, but ((b,b)) and ((d,d)) are missing. Step 3: Identifying missing diagonal pairs is the key.
