If youspecify that the HTTPS listener sends requests to the instances on port 80, the load balancerterminates the requests and communication from the load balancer to the instances is notencrypted, if the HTTPS listener sends requests to the instances on port 443, communication fromthe load balancer to the instances is encrypted. Option A is invalid because there is a need for secure traffic, so port 80 should not be used Option D is invalid because for the HTTPS listener you need to use port 443 For more information on HTTPS with ELB, please refer to the below Link:
