An Organization Is Purchasing Licensed Software

An organization is purchasing licensed software. The software license can be registered only to a specific MAC Address. The organization is going to host the software in the AWS environment. How can the organization fulfil the license requirement as the MAC address changes every time an instance is started/stopped/terminated?

A) It is not possible to have a fixed MAC address with AWS.
B) The organization should use VPC with the private subnet and configure the MAC address with that subnet.
C) The organization should use VPC with an elastic network interface which will have a fixed MAC Address.
D) The organization should use VPC since VPC allows to configure the MAC address for each EC2 instance.
