Which scaling strategy should a solutions architect recommend to meet these requirements?

A. Implement dynamic scaling with step scaling based on average CPU utilization from the EC2 instances.

B. Enable predictive scaling to forecast and scale. Configure dynamic scaling with target tracking.

C. Create an automated scheduled scaling action based on the traffic patterns of the web application.
