Why is the universal relation (A\times A) transitive on any set (A)?

Answer and explanation

Correct answer: Because every ordered pair of elements of (A) is in the relation

Step 1: If ((a,b) \in A\times A) and ((b,c) \in A\times A), then (a,c \in A). Step 2: Hence ((a,c)) is also in (A\times A). Step 3: In a universal relation, no required ordered pair is missing.
