zones without instances are useless, and B is actually more in alignment with the documentation:
First, launch EC2 instances in all the Availability Zones that you plan to use. Next, register these instances with your load balancer. Finally, add the Availability Zones to your load balancer. After you add an Availability Zone, the load balancer starts routing requests to the registered instances in that Availability Zone. Note that you can modify the Availability Zones for your load balancer at any time
answer is D though for exam purposes
