Exam PMP topic 1 question 1382 discussion

A project manager is working on a software development project. The project manager and the project team identified the project risks. As the project progressed one of the risks materialized and the project manager referred to the risk management plan to determine how to manage the risk. Once the risk management strategy was chosen and implemented the risk was closed.

At what point did the project manager move the risk from the risk register to the issue log?
