Question: What does the `notFulfilledState` field with a value of `DEGRADED` indicate in the context of intent fulfilment in mobile networks?
Option 1: The initial state after an intent is received and acknowledged by the MnS producer.
Option 2: A state indicating that the intent was previously fulfilled but no longer meets the initially stated requirements after a period of observation.
Option 3: A condition where the MnS consumer has terminated the specific aspect of the intent, such as updating the intent to eliminate a particular target.
Option 4: The default state for an intent that is compliant with fulfilment requirements but has not yet been fully actioned upon.
Explanation: The `notFulfilledState` with a value of `DEGRADED` indicates a scenario where an intent, previously considered fulfilled, no longer meets the initial requirements after some time, reflecting a change in status due to observed conditions.
