A. B. C. D.Answer - C & D.
The AWS documentation mentions the following on Elastic IP addresses.
An Elastic IP address doesn't incur charges as long as the following conditions are true:
· The Elastic IP address is associated with an Amazon EC2 instance.
· The instance associated with the Elastic IP address is running.
· The instance has only one Elastic IP address attached to it.
If you've stopped or terminated an EC2 instance with an associated Elastic IP address and you don't need that Elastic IP address any more, consider disassociating or releasing the Elastic IP address.

https://aws.amazon.com/premiumsupport/knowledge-center/elastic-ip-charges/An Elastic IP (EIP) address is a static public IP address that can be associated with an Amazon Web Services (AWS) resource, such as an Amazon Elastic Compute Cloud (EC2) instance, a Network Interface, or a Network Load Balancer. AWS customers can use EIPs to mask the failure of an instance or software by quickly remapping the address to another instance in their account.
When it comes to charging, AWS charges for using Elastic IP addresses in the following cases:
When the Elastic IP is associated with a running instance: AWS charges for each hour or partial hour that an Elastic IP is associated with a running instance, even if the instance is not actively using the Elastic IP.
The instance has only one Elastic IP address attached to it: AWS charges for each hour or partial hour that an instance has an Elastic IP attached to it, regardless of whether the Elastic IP is associated with the instance.
Therefore, options A and B are the correct answers.
AWS does not charge for Elastic IP addresses in the following cases:
Elastic IP is associated with a stopped instance: AWS does not charge for Elastic IP addresses when they are associated with a stopped instance. However, if the Elastic IP is associated with a running instance, and then the instance is stopped, AWS charges for the Elastic IP address until it is disassociated from the instance.
You have dissociated the Elastic IP address: AWS does not charge for Elastic IP addresses that are not associated with a running instance or a Network Interface.
Note that there are additional charges for using Elastic IP addresses when they are used with other AWS services, such as NAT Gateways, AWS Site-to-Site VPN, and AWS Direct Connect.
