A region is a geographical location containing one or more data centers that are connected by a low-latency network. It is a part of the global network infrastructure of a cloud computing provider. The primary purpose of a region is to enable customers to deploy their applications and services closer to their end-users, thereby reducing latency and improving performance.

Let's go through each answer option to understand which one defines a Region appropriately:

A. Collection of Data Centers is Region: This is partly correct, as a region can contain one or more data centers. However, a region is not just a collection of data centers; it also includes a low-latency network that connects these data centers.

B. There is One Zone per Region: This is not correct. A region can contain multiple zones, which are isolated locations within a region that are designed to be independent of each other in terms of power, cooling, and network connectivity.

C. Collection of Zones is Region: This is partly correct, as a region can contain multiple zones. However, a region is not just a collection of zones; it also includes one or more data centers that are connected by a low-latency network.

D. There is One Data Center per Region: This is not correct. A region can contain one or more data centers, depending on the cloud provider's infrastructure.

Therefore, option A is the most appropriate definition of a region among the given options.
