   A SaaS company runs a Node.js application in production. They want to reduce alert fatigue while still detecting real failures. Currently, they alert on every ERROR-level log. The application logs expected business rule violations (e.g., invalid input) as ERROR, and also logs transient network timeouts as ERROR. Which logging strategy should they adopt?

   • ALog business rule violations as WARN and network timeouts as ERROR, then alert only on ERROR entries.
   • BKeep all events as ERROR but suppress alerts for messages containing 'invalid input' using a filter.
   • CChange all ERROR logs to INFO so that no alerts are triggered, and rely on manual log review.
   • DLog everything at DEBUG level and set up alerts on any DEBUG entry that contains the word 'error'.
