If (R) and (S) are symmetric relations on a set (A), what is true about (R \cap S)?

Answer and explanation

Correct answer: (R \cap S) will be symmetric

Step 1: If ((a,b) \in R \cap S), then ((a,b)) is in both (R) and (S). Step 2: Since both are symmetric, ((b,a)) is in both, so ((b,a) \in R \cap S). Step 3: Intersection preserves the reverse-pair condition.
