By implementing FSLogix Cloud Cache, you achieve an effective disaster recovery solution for user profiles in your Azure Virtual Desktop deployment across multiple Azure regions, while significantly reducing administrative overhead and ensuring business continuity for your users.

As the question never mentions FSLogix as the profile solution, then CCD would be more administrative effort to set up from scratch. Answer is therefore B Az Site Recovery.
