Let \(A\) be a finite set with \(n\ge2\) elements. Which bound on the number of ordered pairs in \(R\) is guaranteed for every equivalence relation \(R\) on \(A\)?

✅ Step-by-Step Solution

Final Answer: Option (B): Greater than or equal to \(n\)
  1. Reflexivity requires all \(n\) diagonal pairs, so \(|R|\ge n\).
