Correct answer & explanation
✓
Use auto-refresh and clear alert thresholds
For a real-time sales dashboard, the critical design principle is to ensure data freshness and immediate actionability. Option B is correct because auto-refresh keeps the dashboard current without manual intervention, and clear alert thresholds enable the team to instantly identify when sales metrics deviate from expected ranges, which is essential for real-time monitoring.
