Choosing Availability Zones is the appropriate option to ensure the use of Azure datacenters with independent power and cooling. Availability Zones are essentially physically separate datacenters within an Azure region that provide high availability and resiliency. Each zone has its own independent power source, cooling, and networking, which allows for robust disaster recovery and fault tolerance.

When you deploy resources across multiple Availability Zones, you can maintain application continuity even in the event of an outage affecting one zone. This design ensures that your applications remain available and perform well, as different zones can handle the load independently.

Other features like geographical distribution refer to the broader concept of having resources spread across different regions rather than focusing on the independent infrastructure of datacenters. Service-Level Agreements (SLAs) provide guarantees about uptime and connectivity but do not specifically address the physical infrastructure characteristics. Resource Manager is primarily concerned with resource deployment and management in Azure, lacking the consideration of power and cooling independence across datacenters.
