Which scenario is a use case for the Wait step?

This scenario is a use case for the Wait step because it involves pausing a case until another case reaches a certain status. The salary increase case can be configured to wait for the approval case to reach a Resolved-Approved status before continuing to process the increase. The other scenarios do not involve pausing a case based on a timer or a case dependency, but rather on user actions or inputs. References: https://academy.pega.com/topic/case-workflow-dependency/v1
