B is correct: <wants to be notified by email> means SNS. <EC2 instances in an Auto Scaling group> means this should be triggered by auto scaling group A, C and D: no mention of both SNS and auto scaling group

Selected Answer: B
i think B is correct , but Option A is incorrect because, this would only be triggered if an instance was already running and experiencing issues. It would not provide notification when an instance fails to launch.
