Question: What is the criterion for an alarm to be considered 'active' in the AlarmList, allowing its record to be maintained by the MnS producer?
Option 1: The perceivedSeverity is not "CLEARED" or, if "CLEARED", the ackState is not "ACKNOWLEDGED" and acknowledgement by the consumer is supported.
Option 2: The alarm has been acknowledged by the consumer and its perceivedSeverity is "WARNING".
Option 3: The alarmRecord.alarmId matches a specific criterion defined in the NRM AlarmList object.
Option 4: The MnS producer is in an enabled state when creating the AlarmList MOI.
Explanation: This option correctly outlines the criteria for an alarm to be considered active. An alarm is active if its perceivedSeverity is not "CLEARED", indicating it still requires attention, or if its perceivedSeverity is "CLEARED" but has not been acknowledged (ackState is not "ACKNOWLEDGED") when consumer acknowledgement is supported.
