Services and Pods in Kubernetes are ______ objects.

JSON is a data format often used to represent Kubernetes objects when interacting with the REST API, but the objects themselves are not inherently JSON.

YAML is a human-friendly data serialization standard commonly used for defining Kubernetes object configurations, but it is a format, not the object's fundamental nature.

Java is a programming language and has no direct bearing on the fundamental nature of Kubernetes objects.

Kubernetes implements a RESTful API, meaning that all resources like Pods, Services, Deployments, etc., are treated as REST objects that can be manipulated using standard HTTP methods (GET, POST, PUT, DELETE).
