Route 53 is a DNS managed by AWS, but nothing prevents you from running your own DNS (it's just a software) on an EC2 instance. The trick of this question is that it's about EC2, running some software that needs a fixed IP, and not about Route 53 at all.

"Create a Load Balancer and an auto scaling group" - Load balancers do not provide an IP, instead they provide a DNS name
