The correct answer is C. Build dtSearch Index . In Relativity, Automated Workflows consists of two major components: triggers and actions . Triggers determine when a workflow starts, while actions determine what task the workflow performs once it begins. Relativity’s official Automated Workflows documentation lists Build dtSearch index as one of the available actions that can be added to a workflow. When selected, this action allows the workflow to automatically build a dtSearch index, either as a full build or incrementally depending on the configuration.

The other options are not actions. Scheduled Run and Manual Start are both documented by Relativity as trigger types , not actions. Scheduled Run starts a workflow on a defined daily, weekly, or hourly cadence, while Manual Start allows a user to launch the workflow by clicking the Manual Run button. Build a cluster is also not listed by Relativity as an Automated Workflows action. From an RCA perspective, it is important to distinguish triggers from actions because workflow design depends on choosing the correct combination of each. Administrators may configure a trigger such as Scheduled Run or Manual Start, and then assign one or more actions such as Run OCR Set, Run Imaging Set, Build Elasticsearch index, or Build dtSearch index . Therefore, among the options provided, the only valid available action is Build dtSearch Index .
