C.
Detailed monitoring will send data every minute without additional charges

Explanation:
CloudWatch is used to monitor AWS as well as the custom services. It provides either basic or detailed monitoring for
the supported AWS products. In basic monitoring, a service sends data points to CloudWatch every five minutes, while
in detailed monitoring a service sends data points to CloudWatch every minute. Auto Scaling includes 7 metrics and 1
dimension, and sends data to CloudWatch every 5 minutes by default. The user can enable detailed monitoring for Auto
Scaling, which sends data to CloudWatch every minute. However, this will have some extra-costs.
