Detailed explanation-1: -C. Availability Zones contain edge locations.
Detailed explanation-2: -Both the Edge Locations (EL) and Availability Zones (AZ) are AWS Data Centers, but EL are primarily used for caching of the data to provide better user experience with low latency, the AZ are used for hosting servers, websites, applications, softwares, Big Data processing, analytics and a wide variety of use cases.

Detailed explanation-4: -Which statement BEST describes the relationship between Regions, Availability Zones and data centers? Regions are clusters of Availability Zones.
Detailed explanation-5: -The statement “An availability zone’s name (for example, us-east-1a) may change across AWS accounts” is true, as different accounts may remap AZs to different names to ensure better resource distribution.
