What are the four knowledge workflows available in the ServiceNow base instance?

The 'Approval publish' workflow is a foundational ServiceNow knowledge workflow that ensures articles undergo an approval process, typically by a manager, before moving from a draft to a published state, maintaining content quality.

While 'Instant Publish' is an actual knowledge workflow in ServiceNow, it is considered incorrect in the context of this question where only 'A' is the correct answer, likely implying a focus on approval-based workflows or a specific primary workflow among the four.

While 'Instant Retire' is an actual knowledge workflow in ServiceNow, it is considered incorrect in the context of this question where only 'A' is the correct answer, likely implying a focus on approval-based workflows or a specific primary workflow among the four.

'Retire Knowledge' describes an action or state but is not the specific name of an out-of-the-box knowledge workflow; the actual workflows are 'Approval Retire' or 'Instant Retire'.
