Answer: B

Explanation:

The best strategy to migrate the current on-premises workloads to the public cloud for the company that requires at least 80 instances running at all times and wants the workload to be highly available and cost-effective is to create /26 subnets in two regions and run 40 instances on each one. A /26 subnet can accommodate up to 62 hosts, which is enough for 40 instances. By creating subnets in two regions, the company can achieve high availability and redundancy in case one region fails due to a catastrophe. By running 40 instances on each subnet, the company can meet the minimum requirement of 80 instances and also save on costs by avoiding overprovisioning or underutilization of resources.
