Initially I chose A but then again, "highly available and scalable" should indicate multi az and auto scaling group, so C is the only valid option.

AnswerC I would de-couple as many elements as possible with appopriate redundancy (HA), hence Auto-Scale in 2 AZ for EC2, Database in Multi-AZ and ALB infront of EC2. It will allow to increase amount of servers in case of need and will prevent from service unavailability in case if something fail ;)
