A readiness probe is a critical component in Kubernetes that determines if a container within a pod is prepared to handle incoming traffic. This verification process is essential for maintaining application reliability and user experience, as it allows Kubernetes to manage the routing of requests only to those containers that are ready to serve them.

When the readiness probe indicates that a container is not ready, it will prevent the container from receiving traffic, ensuring that requests are not sent to an application that is still initializing or encountering issues. This helps in maintaining a robust service that can effectively handle fluctuations in load without exposing users to downtime or errors from partially started applications.

By contrast, the other options focus on different aspects of container and pod management that do not relate directly to the readiness of accepting traffic. Thus, the role of the readiness probe is uniquely suited to indicator B.
