Portworx classifies every alert into one of three severities to indicate urgency and recommended operator action. The official Portworx alert documentation states that each alert is tagged as either INFO (informational, no action), WARNING (requires attention soon), or CRITICAL (requires immediate action). These are the only three severities defined in the product, so option B is the exclusive correct choice.

A. Uses “ERROR”; Portworx never assigns “ERROR” as an alert severity.

C. Uses “ALARM”; “ALARM” is not a recognised severity label in Portworx alerts.
