  C https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-recover.html In the event that AWS determines an instance is unavailable due to an underlying hardware issue, there are two mechanisms that you can configure for instance resiliency which can restore availability—simplified automatic recovery and Amazon CloudWatch action based recovery. This process is called instance recovery. The following are examples of underlying hardware issues that might require instance recovery: - Loss of network connectivity - Loss of system power - Software issues on the physical host - Hardware issues on the physical host that impact network reachability

  C. This is the correct solution. By creating a CloudWatch alarm for the StatusCheckFailed System metric and configuring the alarm to trigger the "Recover this instance" action, the EC2 instance will be automatically recovered in the event of a system failure or power outage. This ensures the instance can be quickly recovered with minimal data loss, as the EBS volume remains attached during the recovery process. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-recover.html
