For me also, B seems to be a suitable option. For D we need to manually create CW events, while we can use inbuilt ASG events feature

C is the correct answer. EC2 cannot send notifications to SNS topics. We need to use cloudwatch events for this. { "source": [ "aws.autoscaling" ], "detail-type": [ "EC2 Instance Launch Unsuccessful" ] }
