Explanation

Option C is the best solution to ensure the durability and availability of log data from EC2 instances in an Auto Scaling group. By using an Amazon CloudWatch agent, the logs can be sent to Amazon CloudWatch Logs, which is a fully managed service that can store, monitor, and analyze log data. CloudWatch Logs also allows you to set retention policies for your log groups, so you can keep the logs for a minimum of 1 year for auditing purposes. CloudWatch Logs also supports encryption, access control, and compliance features to protect your log data.
