An alert 'HighErrorRate' fires when the error rate exceeds 5% for 10 minutes. The alert is routed to a receiver that sends an email. The team notices that the alert fires repeatedly, but they only want to be notified once when the condition starts, not on every evaluation while the condition persists. What should be configured to achieve this?

Set 'repeat_interval: 0s' in Alertmanager to disable re-notifications.

Remove the 'for' clause so the alert fires immediately and then resolves quickly.

Set 'for: 10m' in the alerting rule and configure Alertmanager's 'repeat_interval' to a very long duration.

Use a recording rule to suppress the alert after the first notification.
