Which of the following scenarios allows a user to run a flow that is not currently active?

The option indicating that a user can run a flow that is not currently active because they are a flow admin with Manage Flows permission is correct. In Salesforce, users with the Manage Flows permission have the authority to run inactive flows. This role provides them with the capability to test flows or perform administrative tasks that require access to the flow irrespective of its activation status. This feature is especially useful in development or testing environments where flows are often updated and may not yet be active for general user access.

Other scenarios may not support running an inactive flow. For instance, being a system admin does not grant the ability to run inactive flows unless the flows have been marked as active. Similarly, a process builder can only invoke an active flow and cannot directly run a flow that has been deactivated. Embedding in a utility bar typically allows for access to components that are already functional, which doesn’t apply to inactive flows. Thus, the ability to run an inactive flow lies specifically with the permissions associated with flow administration.
