Explanation

EIP (Elastic IP Address) is AWS's term for a static, permanent public IPv4 address that you can allocate to your account and associate with EC2 instances or other resources - it persists until you explicitly release it, even if the instance is stopped or replaced.

Why the distractors are wrong:

• A (Reserved IP) is not an AWS term; it's a generic concept used in some other cloud/networking contexts.
• B (PIP) stands for "Public IP" in Microsoft Azure, not AWS.
• D (Floating IP) is the equivalent concept in OpenStack and DigitalOcean, not AWS.

Memory tip: Think of the "E" in EIP as Elastic = Enduring - just like Elastic Load Balancers and Elastic Block Store, AWS uses "Elastic" to mean the resource flexibly persists and can be detached/reattached across your infrastructure.
