Performance efficiency relates to optimizing resources for performance, not application recovery.
Operational excellence involves monitoring and operations management, but not specifically about recovering applications.
Reliability pertains to the ability of a system to recover from failures, which is directly addressed by the Auto Scaling and Load Balancer implementation.
If I’m correct, the answer is:
Reliability
