Answer A. Hint: low network latency. Cluster placement groups are placed very close to each other to avoid latency issues.

Explanation: When you launch a new EC2 instance, the EC2 service attempts to place the instance in such a way that all of your instances are spread out across underlying hardware to minimize correlated failures. You can use placement groups to influence the placement of a group of interdependent instances to meet the needs of your workload.
