The recover action can be used only with StatusCheckFailed_System, not with StatusCheckFailed_Instance. -> I will go with C

No, the question mentions that "EC2 instance that is backed up by Amazon EBS storage", if you use ASG, you need to configure based AMI, which means data loss more, I will choose C.
