A company runs an application on hundreds of Amazon EC2 instances in three Availability Zones. The application calls a third-party API over the public internet. A SysOps administrator must provide the third party with a list of static IP addresses so that the third party can allow traffic from the application.
Which solution will meet these requirements?

A. Add a NAT gateway in the public subnet of each Availability Zone. Make the NAT gateway the default route of all private subnets in those Availability Zones.

B. Allocate one Elastic IP address in each Availability Zone. Associate the Elastic IP address with all the instances in the Availability Zone.

C. Place the instances behind a Network Load Balancer (NLB). Send the traffic to the internet through the private IP address of the NLB.

D. Update the main route table to send the traffic to the internet through an Elastic IP address that is assigned to each instance.
