What does the Prepare Only action do on a prioritized review queue?

The correct answer is B. Runs the saved search and trains the classifier. Relativity’s Review Center documentation states that during the Preparing state, the queue is refreshing the saved search for the first time , and for a prioritized review queue , this also trains the classifier . The Review Center admin quick reference guide further states that Prepare Only re-runs the saved search for all queues and retrains the AI classifier for prioritized review queues , and it does not start the queue.

That makes option B the direct documented effect of Prepare Only. It does not grant reviewer access by itself, it does not release checked-out documents, and it is not a statistical sampling action. From a case administration perspective, Prepare Only is used to get the queue ready and refresh the machine-learning state before reviewers begin or resume work. Therefore, the correct answer is B .
