A) Eliminated - We need custom metrics. default EC2 metrics (such as CPU utilization, network traffic, etc.) are not related to the specific values generated by the application.

I was erroneously voting for A but this is not correct because it says "reported by default" but we need to analyze the value that the EC2 instances create. For do that we can use the SDK to create a standard resolution custom metrics and send it to Cloudwatch. So, the C is definitely the right answer
