A. Headless Service Here's why: Headless Service: This type of service doesn't have a cluster IP address assigned. Instead, it maps directly to the pods it manages, allowing communication with individual pods using their unique IP addresses. Nodeless Service: This term isn't commonly used in Kubernetes. Services can exist and function even without a dedicated node running them. IPLess Service: While this might seem like a logical term, "Headless Service" is the official designation in Kubernetes. Specless Service: A service definition requires a specification file (usually YAML). A service without a spec wouldn't be a valid service at all
