On (A={0,1,2,3,4}), (R={(a,b):a^2\equiv b^2 \pmod{4}}). What is the correct reason for (R) being reflexive?

Answer and explanation

Correct answer: For every (a), (a^2\equiv a^2 \pmod{4})

Step 1: To test reflexivity, check ((a,a)). Step 2: The condition becomes (a^2\equiv a^2 \pmod{4}), which is true for every element. Step 3: Equality or same-remainder conditions usually include all diagonal pairs.
