C: Correct: Access review policy can request the owner to check the membership for guest every 30 days.

C. access reviews. Access reviews are designed specifically for the purpose of regularly reviewing and re-validating user access, including guest user access, to Microsoft 365 groups. You can set them up to recur at a defined interval (like 30 days) and require group owners to confirm that each guest user still needs access. Here's why the other options are not the best fit: Group expiration policies: These are used to automatically expire and delete groups after a certain period of inactivity. This doesn't address the specific need to validate guest user membership. Retention policies: These are focused on preserving or deleting data, not on managing user access. Conditional Access policies: These are used to control access to resources based on conditions like location, device, and user risk. While they can be part of a security strategy, they don't directly address the requirement for periodic guest user validation. https://learn.microsoft.com/en-us/entra/id-governance/access-reviews-overview
